高峰矿深部多空区下充填采矿地压分布特征

Ground Pressure Distribution Features under Filling and Mining of Deep Multiple Mined-out Areas of Gaofeng Mine

针对高峰矿在高应力、局部矿岩破碎、多空区充填体等复杂环境下开采回采工作的安全与效率受到严重影响的状况,利用ANSYS-Workbench平台建立高峰矿开采数值模型,导入FLAC3D软件进行计算分析,研究高峰矿深部地压分布特征,提出针对性地压控制措施,为深部回采设计与生产提供指导。

In view of the production safety and efficiency badly threatened by the complex conditions of high stress, local broken ore rocks and multiple mined-out areas in Gaofeng Mine, the numerical model of Gaofeng mine is established with the use of ANSYS-Workbench and imported in FLAC3D to compute and to study the distribution law of ground pressure. The targeted advices of ground pressure control measures are proposed to guide the deep stoping design and mining.
