Layered Excavation of the Third Potash Seam with Reduced Thickness of Interlayer Ceiling

The third potash seam of the Starobinsky deposit is mainly mined using the layered mining technology. The essence of the technology lies in the advance excavation of the 4th sylvinite layer by the uppere lava and the joint excavation of layers 2, 2–3 and 3 by the lagging lower lava under the protection of the interlayer pack of rock salt 3–4 (ceiling) left in the goaf. The thickness of the ceiling in accordance with the requirements of the regulatory document should be at least 0.8 m. At the same time, in the mine field of the mine of the Third Mine Administration, there are areas with a ceiling thickness reduced to 0.66–0.70 m. The purpose of the author’s research was to determine the possibility of safe mining of the Third potash seam using the layered mining technology with a reduced thickness of the ceiling. In the course of a full-scale experiment, the geological structure and strength properties of the rocks of the ceiling, its stability in the bottomhole space and the intensity of loading of the bottomhole lining of the lower lavas have been studied in the paper. The research methods also included the analysis of literary sources and statistical processing of the obtained data. It has been established that a decrease in the thickness of the ceiling by 0.10–0.14 m from the required one does not have a significant effect on its strength, while it remains stable in the near-bottom space of the lower longwalls. The main indicators of the manifestation of rock pressure in the studied lower longwalls – the rate of increase of the bottomhole lining in the stope cycles and the lowering of the roof in the bottomhole space – did not exceed the similar indicators in the longwalls with the required thickness of the ceiling. The obtained data indicate the possibility of safemining of the Third potash seam using the layered excavation technology with the thickness of the interlayer rock salt pack 3–4 not less than 0.66 m. In this case, the bearing capacity of the bottomhole lining should be at least 550 kN/m2.

The Achievement and Interpretation of Balhae Relics in Korea

In this article, I looked at how Balhae relics were excavated and analyzed in Korea. Specifically, we covered Balhae-related dissertations in Korea, and then dealt with the subject through the paper. The Balhae sites exist in Russia, China and North Korea. Korean scholars are in a very difficult environment to directly investigate Balhae ruins in Russia, China and North Korea. Despite such limitations, it is encouraging that the number of scholars who have obtained master s and doctorate degrees under the theme of Balhae Temple has been steadily increasing until recently. In addition, it is in the process of overcoming the limitations of the literature while dealing with the excavation achievements of China, Russia and North Korea. This indicates that we have entered the stage where we can refer to the results of fieldwork and excavation of Balhae sites. In addition, the increasing number of Ph.D. researchers in China and Russia are studying abroad shows that the Balhae history research community is deepening in that it is expanding the scope of the Balhae history research environment. Although the number of Balhae history researchers in Korea is smaller than that of Goguryeo. However, Korea is competitively expanding its Balhae history research level as it continues to conduct in-depth analysis and interpretation. It is hoped that researchers from Balhae history in Korea will be able to conduct joint excavation research with scholars from China and North Korea. Until now, researchers at Balhae history in Korea have only been engaged in exchanges with Russian researchers, limited to partial sites in the Russian coastal province. Over one thousand years ago to Balhae was in East Asia the hub of cultural exchange. Haedong Seongguk(海東盛國) which was praised as one of the Balhae, and now the current geographical area classification of the country, and Balhae be the remains of access is restricted. I hope this study will lead to a comprehensive investigation into Balhae ruins.

The 2014-2015 excavations of the Zhouyuan Site in Baoji, Shaanxi

AbstractIn the years 2014 and 2015, the Joint Excavation Team at Zhouyuan conducted excavations of the rammed-earth foundations in the northern area of Hejia Village, a residential-burial area, a chariot-and-horse pit and a horse pit centered by the Fengchu palace complex, as well as five ponds and canals in a water reticulation system. The artifacts found in the rammed-earth foundations include golden foil objects, turquoise pieces, protoporcelain artifacts, lacquer objects, jades and cowry shells. The features found in the residential-burial area include burials, ash pits and house foundations, and these features contained artifacts such as bronzes, pottery and proto-porcelain vessels, jades, stone implements and lacquer objects. The excavations of the five ponds and canals in the water reticulation system and the previous fieldwork results showed that there was a well-planned water reticulation system consisting of the natural river system and an artificial canal system including water ponds, headwater canals, trunk canals and branch canals of different levels at the Zhouyuan Site.

The earliest evidence of hominid settlement in China: Combined electron spin resonance and uranium series (ESR/U-series) dating of mammalian fossil teeth from Longgupo cave

Abstract Longgupo cave, located in Chongqing Municipality, China, was discovered in 1984. Sixteen Gigantopithecus teeth and two hominid fossils accompanied with abundant mammalian fossils and stone artifacts were unearthed from the site. Previous dating result is questioned because of the complexity of deposition history. In this study, seventeen mammalian fossil teeth collected from different layers of unit C II and C III (C III′) during the 2003–2006 Sino-Franco joint excavation were analyzed by combined ESR and U-series methods, and calculated with a US-ESR model. In situ dose rates were remeasured in detail in 2012, in order to refine the external dose rate determination. Uranium-series analyses indicate that no obvious uranium leaching has occurred, and all the teeth underwent a very recent uranium uptake history, except one from layer C III 3 of the south wall. The US-ESR results show that the ages of ten teeth from unit C III′ of the north wall are consistent in general, about 2.35 Ma. The ages of seven samples from south wall are not in accordance with the stratigraphic order: three teeth are much younger than the other four, probably attributed to the relative higher uranium concentration and U/Th ratio in the dental tissues and significant higher in situ gamma dose rate. Nevertheless, the three teeth from C III of the south wall give an average age of ∼ 2.48 Ma. The fossil ages obtained in this work combined with paleontological evidence and new paleomagnetic results place Longgupo at the very beginning of the Early Pleistocene. Compared with other early hominid settlements, Longgupo is one of the earliest evidences of hominid settlement in China and East Asia to date.

The John Street Methodist Church: An Archaeological Excavation with Native American Cooperation

During construction work at the historic John Street Methodist Church in Lower Manhattan in New York city, workers found human bones near the foundation wall of the church. The minister and church leaders voluntarily halted the project so that archaeological work could be undertaken. Since the property had the potential to contain Native American or European American burials, the City Archaeology Program and the American Indian Community House undertook a joint excavation of the site. This was the first time in New York City that Native Americans worked on an archaeological excavation. No other human remains were found, but many artifacts from the mid-19th century were uncovered. The artifacts provide glimpses into the social behavior of the congregation.

Agriculture irriguée et art bouddhique ancien au cœur du Taklamakan (Karadong, Xinjiang, IIe-IVe siècles) [Premiers résultats de l'expédition franco-chinoise de la Keriya

The Sino-French Archaeological Expedition in Keriya has been settled in the frame of an official program of field cooperation signed between the UPR n° 315 in CNRS (France) and the Institute of Archaeology in Xinjiang. In a first stage, the program is focussed on the exploration of the Keriya valley in Southern Xinjiang (Khotan region). The aim is to find remains of an ancient human occupation along the ancient dry courses and deltas of the river, to date this occupation, and to study it in relation with the moves of the river in an environment turning into a desert. A first survey has been conducted in 1991. New sites has been discovered which are the vestiges of an ancient oasis approximatively dated between the 2nd and the 4th centuries A.D., with Karadong as the center of it. In 1993, a joint excavation has been carried out at Karadong (the first joint excavation undertaken in China since 1949). New archaeological remains has been discovered, including houses, craft areas, irrigation canals, traces of fields and orchards, ceramics showing contacts with the Kushan world and Central Asia, objects in metal, wood and glass, fragments of fabrics, etc. We also excavated a small square Buddhist temple with many fragments of wall paintings of an original style, one of the most ancient ever discovered in Xinjiang.

Excavations near Mamousia in Achaia

About four miles south of the modern railway station of Diakophto in Achaia, on a high saddle between the valleys of the rivers known to Colonel Leake as the Bokhusia and River of Kalavryta, just north of the modern village of Mamousia, are the remains of a small walled ancient city. Leake supposed these ruins to be those of the ancient Achaean city of Keryneia: later the French Scientific Commission in the Morea identified them with the town of Bura: Leake accepted this view, which prevailed generally until it was refuted by Professor Ernst Meyer of Zürich in 1938. I was not at first inclined to accept all Professor Meyer's arguments; he has, however, courteously answered my objections, and a re-examination of the evidence has convinced me that he is right and that the ruins are indeed those of Keryneia.I visited the ruins at the end of 1950 and in the foundations of a small building above the theatre discovered an antique bronze in the form of the head and neck of a goose. This I took to the National Museum in Athens, where it was cleaned and found to be of such interest that a small joint excavation by Mr. Zapheiropoulos, Ephor of Antiquities, and myself, was agreed upon.This excavation was carried out in May 1951. Unfortunately Mr. Zapheiropoulos was unable to be present himself, but I had the benefit of the guidance of his experienced foreman, Mr. Andreas Mitropoulos.

The First Campaign of Excavation at Beth-zur

In 1926 the first joint excavation of the American School in Jerusalem, at Tell Beit Mirsim, was undertaken by President M. G. Kyle and Dr. W. F. Albright, on behalf of the Xenia Theological Seminary (now the Pittsburgh-Xenia Theological Seminary). The fourth joint campaign at this site is planned for 1932. After the Rockefeller grant was made, Yale University entered into a similar relationship with the School for the excavation of Jerash; the first joint campaign began in 1930 under the direction of Dean C. C. McCown and Professor C. S. Fisher. This summer a third joint undertaking has been added, the excavation of Beth-zur by the Presbyterian Theological Seminary of Chicago. It is expected that this enterprise will be continued for a number of campaigns until the site has been thoroughly studied. The approximate location of Beth-zur has never been lost; but the ruin which now bears this name, situated to the west of the road from Jerusalem to Hebron, opposite 'Ain edh-Dhirweh (Philip's Fountain according to late tradition), represents the Byzantine-Arabic offspring of the ancient town. It was not until 1924 that Pere Abel, of the Dominican Fathers of St. Stephen in Jerusalem, observed that the ruins of Burj es-Sur were too late, and identified the ancient site with Khirbet etTubeiqah, about half a mile to the northwest. Within the same year the American and German Schools made the same observation, quite independently (see BULLETIN, No. 18, p. 9). In 1928 Professor O. R. Sellers was so impressed with the suitability of the site that he determined to excavate it, if possible. This was made possible by the active interest and support of President John Timothy Stone, who secured the funds needed for the purpose from several persons of means living in Chicago and the vicinity. To President Stone and the enlightened donors Palestinian archaeology owes a debt of gratitude. In few recent archaeological undertakings in Palestine has so much new historical material been obtained in so short a time and at so small a cost. The expedition was organized on practically the same basis as the Tell Beit Mirsim campaign of 1930 (see BULLETIN, No. 39). Drs. Sellers, Albright, Schmidt, Glueck, and Saarisalo were again on the staff during this expedition, as were also the surveyors, Labib Sorial, William Gad, and Bulos el-A'raj. Two of the trained Egyptians were also back with us, as were the cook and chauffeur, as well as 'Odeh Jirius, who assisted us with the negotiations and acted as one of the foremen. New members of the staff were Dr. Cyrus Gordon of the University of Pennsylvania, now Fellow at the Baghdad School, and Messrs. Charles Nims of the Presbyterian Theological Seminary and Milton Patterson of the American School at Larnaca, Cyprus. We were fortunate in securing Professor Fisher's chief
