新郑赵家寨煤矿岩层移动及地表沉陷规律浅析

Analysis on the rock movement and ground subsidence Law of ZhaoJiaZhai mine Xinzheng

新郑煤电公司赵家寨煤矿位于新密煤田的东部,为一对大型生产矿井。为保证矿井各类煤柱的合理留设,参照邻近矿区开展岩层移动及地表沉陷规律的研究很有必要。岩层移动及地表沉陷的过程受岩石的物理力学性质、自然地质因素和采矿技术因素等多种因素的影响。本矿区与新密煤田西部地区既有共同点又存在差异性。

ZhanJiaZhai Coal Mine of Xinzheng Coal and Power Company is located in the eastern part of Xinmi coalfield, It is a pair of large - scale production of mine. To ensure that all types of coal pillar left mine set up is reasonable, It is necessary to take into account the neighboring mine ,then to carry out the law of rock movement and surface subsidence research. The process of rock movement and surface subsidence is affected by physical and mechanical properties of rocks, natural geological factors and mining technological factors and other factors. Both commonalities and differences are exist between the mine and the western region in Xinmi coalfield.
