The present situation, problems and countermeasures to deep mining in Huainan and Huaibei coal mining areas

Abstract

Anhui Province, located in the southeast of China, the geographical position is longitude 115o–119o40' and north latitude 29o26'–34o40'. The total area is 139000 square kilometers. The coal resources of Anhui are mainly distributed in Huaibei Coalfield and Huainan Coalfield (Huainan and Huaibei Mining Areas), Carboniferous, Permian coal-bearing strata, followed by the Wannan Coalfield, distribution in the area on the southern side along the Yangtse River. The coal bearing area in Anhui Province is about 1800 square kilometers, which account for 12.9% of the total area of the province. Coal reserves in the province are 273.585656 × 109 tons, in which coal reserves for coal mines in production and construction are 87.466289 × 109 tons, the reserves for the further exploration are 115.891987 × 109 tons. Predicted reserves are 61.15551 × 109 tons, in which reliably predicted reserves is 32.18962 × 109 tons. In Anhui Province all kinds of coal occur, from low metamorphic coal to high rank anthracite.
