Abstract

Surface mining and open pits engineering affect the environment in a very negative way. Among other pollutions that open pits make during mineral deposits exploiting, particular problem is the landscape changing. Along with converting the land into pits, surface mining is connected with pilling dumps that occupy large ground. The article describes an analysis of transportless methods of several coal seams strata surface mining, applied for open pits of South Kuzbass coal enterprises (Western Siberia, Russia). To improve land-use management of open pit mining enterprises, the characteristics of transportless technological schemes for several coal seams strata surface mining are highlighted and observed. These characteristics help to systematize transportless open mining technologies using common criteria that characterize structure of the bottom part of a strata and internal dumping schemes. The schemes of transportless systems of coal strata surface mining implemented in South Kuzbass are given.

Highlights

For the last decade coal mining in Kuzbass increase by 6-10 million tons annually
Transportless methods allow efficient developing the several flat or inclined coal seams strata with a total capacity of 50 m or more, along with forming three-layers dumps of overburden rock
Analysis of the parameters of coal seams bedding in strata showed that according to the conditions of seams bedding in the strata the structures of geological sites can be divided in terms of, which characterizes the type of structure of the lower part of strata to a height of two seams and their interbed

Summary

Introduction

For the last decade coal mining in Kuzbass increase by 6-10 million tons annually. The transportless system of surface mining may significantly decrease the earth consumption but requires more complicated technological schemes of coal deposit exploiting [5,6,7,8,9]. Special difficulties appear when transportless mining system is implemented for the strata of several coal seams development [10,11,12,13,14]. Transportless methods allow efficient developing the several flat or inclined coal seams strata with a total capacity of 50 m or more, along with forming three-layers dumps of overburden rock. Often there is an excess of transportless quarry face over transport one that leads to leads to a reduction in the volume of rock
