深部工作面回采巷道锚网支护设计与优化

Design and Optimization of Anchor Network Support for Deep Working Face Mining Roadway

为了确保回风巷及首采面在煤矿开采时的稳定,以张集矿东三11-2煤采区1511工作面为研究对象,针对原围岩的赋存状况和相应的力学性质,通过计算确定相关的力学参数,并通过FLAC3D进行多种锚网支护设计方案的模拟,最终确定了较为合理的回采巷道锚网支护设计,并进行了优化,并验证了该设计的可行性。

In order to ensure the stability of the return wind lane and the first mining face during coal mining,taking the 1511 working face of Dongsan 11-2 coal mining area of Zhangji Mine as the research object,the relevant mechanical parameters were determined by calculation according to the occurrence status of the original surrounding rock and the corresponding mechanical properties,and a variety of anchor net support design schemes were simulated through FLAC3D,and finally a more reasonable anchor network support design of the mining roadway was determined,optimized and the feasibility of the design was verified.
