深部开采条件下走向与倾向移动角关系研究

STUDY ON RELATIONSHIP OF DISPLACEMENT ANGLE OF THE RUN AND INCLINATION OF COAL LAYER UNDER MINING IN DEEP-LYING CONDITIONSs

随着我国煤矿开采深度的不断增加,指出了目前岩层移动角的确定存在诸多问题。在分析了影响其确定因素基础上,在一定的地质采矿条件下,提出了深部开采条件下岩层移动角的确定方法,探讨了走向移动角与倾向移动角之间的关系。最后,实例验证了岩层移动角确定的合理性,从而为最优设计保护煤柱提供理论依据。

With mining depth increasing continuously in our country, in condition of mining in the deeplying, there are many problems in determining displacement angle of stratum at present. Under the determination geology mining conditions, based on analyzing problem of displacement angle of stratum mining in deep-lying conditions at present, the determination its method is proposed, and its relationship of the run and inclination of coal layer is studied. At last, the reasonable of determination on displacement angle of stratum is verified with example, and theory basis is provided for designing coal pillar.
