放顶煤采场上覆岩层运动规律研究

采场中一切矿压显现的根源是采动引起的上覆岩层运动。由于放顶煤采场上覆岩层的岩性、厚度、层位关系及构造情况不同,运动规律也各异。应用微地震定位监测技术,把对岩层运动的认识观从平面阶段推进到空间阶段,从空间范围内研究放顶煤采场围岩的活动规律,对放顶煤矿压问题的研究具有一定指导作用。

Study on Law of Overlying Strata Movement in Roof-Coal Stope

Origin of strata behavior is overlying strata movement in mining areas. Because of the difference of lithology, thickness,stratigraphical relationship and structure situation of overlying strata in roof-coal stope, motion law is also different. By applyingmicroseismic locating monitoring technology, the view of strata movement is promoted from plane array stage to spatial stage, andthe movement law of wall rock in spacial scale is studied, which is of certain guiding role in the study of mine pressure of roof-coal stope.
