【摘要】 “三下”采煤的安全问题是长期以来在采矿中值得注意的问题,它关系到矿井作业的安全和经济效益问题。本文就在给定的煤层现有开采技术条件下,利用概率积分法的理论和有限元预测在村庄下采煤的地表变形规律,关于村庄下采煤的地表下沉问题通过我国某煤矿的某一个方向地表下沉的实际观测值和用ANSYS软件预测的下沉曲线来做研究与对比,得出了可靠的结论。提出并论证了有限元在村庄下采煤的不同设计参数的模拟效果,从而解决了村庄下采煤的安全问题。更多还原

【Abstract】 Mining under the village ,the railway and the water is a problem in mining,which is related to the safety and the economic benefit in every coal pit. Based on the mining technology, this article puts forward the surface distortion of the mining coal under the village by the method of probability integration and ANSYS with the surficial subsidence example comparison, a reliable conclusion is reached, further more, it puts forward and proves the result of simulation in different design parameters, so it solves the safety problem in Mining under the village.更多还原
