浅埋煤层采场矿压规律及支架合理工作阻力研究

Study on Mine Pressure Law and Reasonable Working Resistance of Bracket in Shallow Coal Seam Stope

在煤场开采时,部分矿井可能会存在覆房采空区和煤柱区,当然,这些现象的发生,也给煤层开采过程增加了难题。接下来,本文通过研究煤层采场矿压规律和支架合理工作阻力理论,使煤矿开采工作时人们能够对矿压规律和支架状况有充分的掌握,同时也能在这其中发现煤矿开采工作的种种问题,从而为开采实际中的难题制定了策略与措施。

In the mining of coal mine,there may be goaf and pillar area in some mines.Of course,these phenomena also add difficulties to the mining process of coal seam.Next,this paper studies the law of mine pressure in coal seam stope and the theory of reasonable working resistance of bracket,so that people can fully grasp the law of mine pressure and the condition of bracket in coal mining,at the same time,people can find various problems in coal mining,so as to formulate strategies and measures for difficult problems in mining practice.
