摘要
针对邯郸煤业 (集团 )有限责任公司郭二庄煤矿 12 4 5切眼帮底为松散软煤的特点 ,用FLAC3 3软件进行了数值模拟研究。结合模拟结果 ,提出了该切眼锚梁网支护主要技术参数。应用实践证明 ,所采取的锚梁网支护技术参数合理正确。
With soft weak coal features in the floor and side walls of an open off cut in No 1245 coal mining face of Handan Guoerzhuang mine, data simulation study was conducted with FLAC 3 3 software. Combined with the simulation results, main technical parameters of the bolt/beam/mesh support for the open off cut were provided. The applied practices show that the technical bolt/beam/mesh support parameters were rational and correct. Those parameters can be the references to the bolt/beam/mesh support in simulate soft weak coal conditions.
