摘要
研究发现引发冲击地压的因素分为内外2个因素,其中煤岩的冲击倾向性属于内在因素,也是引发冲击地压的主要原因。主要介绍某煤矿13煤层及其顶底板岩层的冲击倾向性测定和评估。为该矿今后对冲击地压预测、防治提供必要的科学依据。
Study found that triggered the factors can be divided into two factors both inside and outside of percussive ground pressure, the inclination of the impact of coal and rock belongs to the internal factors,and it also is the main reason for the impact ground pressure. Mainly introduces the impact of the 13 coal seam and its roof and floor rocks measurement and evaluation of a mine.To impact the necessary scientific basis for prevention and control of ground pressure prediction.
