耿村煤矿南部2-1煤与2-3煤合并后,层滑构造发育,导致煤层厚度变化大且呈带状分布,巷道支护困难。通过实地观察和认真总结认为:层滑构造与岩性有关,其源动力为断层的牵引作用。总结了层滑构造对生产的影响,分析了断层与层滑构造的关系,提出了层滑构造对断层的指示作用,具有重要现实意义。
After the combination of 2-1 coal and 2-3 coal in the south of Gengcun coal mine, the strata-slip structure develops, resulting in large thickness variation and belt-like distribution of the coal seam and difficulty in roadway support. Through field observation and careful conclusion, it is concluded that the slip-shear structure is related to lithology, and the source power is the traction effect of the fault. The influence of the stratified slip structure on the production is summarized. The relationship between the fault and the slip-shear structure is analyzed, and the indication of the slip-shear structure on the fault is proposed. This is of great practical significance.
