连续采煤机适采煤层的地质评估与储量预测

Geological assessment and prediction of coal seams suitable for continuous miner

该文是在广泛调查国内外连续采煤机的使用情况的基础上,对全国统配局矿主采煤层的矿山地质条件进行了调查,是当前煤炭系统有关部门较关注的问题之一。

introduction of continuous mines in the past few years has aroused extensive concern of coal mines in China. This paper makes use of 10 factors, such as dip angle, thiokness and properties of coal seams, occurrence depth,properties of roof.and floor, geological structures, gas, coal dust etc. as criteria for assessing geological classes. Based on comprehensive analysis of relations among men, machine and coal bearing rockmass. the classes of coal scams suitable for continuous mining are determined, and on the basis of which,the layer or section of seam and their reserves suitable for continuous mining are predicted. The author has listed 6 faces where tests have been made or tests to be made in China as examples for assessment and prediction of reserves of coal seam or section of seam suitable for continuous miners in 158 Chinese coal mines.
