| 摘 要： | 为解决峰峰集团新三矿建筑物下压煤量大的现状,利用膏体充填技术进行开采.本文以矿区两个工作面为例,运用概率积分法原理,分别对全部跨落法和膏体充填开采地表移动变形情况进行预计,通过预计结果比较得出:建筑物下膏体充填技术在提高煤炭采出率的同时,能够减小地表移动变形,减少地表破坏范围.膏体充填开采是煤炭绿色开采技术的重要组成部分,开展该技术的应用研究,是缓解我国煤炭资源紧张形势、实现矿山可持续发展的有效途径.

| Abstract: | In order to solve the situation of a large number of coal covered by buildings in Xinsan mine,Fengfeng Group,we used technology of paste filling during mining.This paper took two working faces in mining area as examples,using the theory of probability integral method to predict surface movement and deformation when mined by fully caving method and paste filling method separately.Comparing the predicted results,it was gained that paste filling technology under buildings can not only increase the rate of coal... |
