摘要
以淮浙煤电公司顾北煤矿的1262(1)综采工作面为工程背景,通过计算机数值模拟和现场实测等研究方法,对深井开采的矿压特征和围岩控制技术进行了研究,采用FLAC3D对不同深度采场进行数值模拟,分析比较浅部与深部采场其超前支承压力的变化特征,为深井工作面的安全高效生产提供了指导。
Taking the 1262（1） working face in Gubei Coal Mine of Huaizhe Coal-Electricity Company as the project background,though many research techniques such as the computer numerical simulation and field measurement,the mining ground pressure feature and control technology of surrounding rock in deep mining are analyzed.FLAC3D is used to carry out the numerical simulation on different depth stope.The shollow and deep mine stope,and the variation of advance support pressure are analyzed and compared.The guidance is provided for the safe and high effective production at the deep mine faces.
