基于应力预调控的采区防冲设计

Outburst Prevention design of mining area based on stress precontrol

徐矿集团张双楼煤矿-1 000 m延深下山采区基于应力预调控,从开拓布置、保护层的选择、采区主系统巷道层位布置、工作面停采线位置优化、采区内9煤巷道与7煤煤柱距离优化、7煤和9煤工作面开切眼距离优化、相邻工作面区段煤柱宽度优化、各工作面接替顺序优化等方面进行采区防冲设计,实现从源头上防范冲击地压。

In this paper,based on stress precontrol,-1 000 m deep downward mining area of zhangshuanglou Coal Mine of Xuzhou Mining Business Group Co.,Ltd.,a series of optimization were applied into field production,from the development layout and the choosing of protection layer,the level layout of main roadway,the location optimization of stopping line of the working face,the optimization of distance between 9 coal roadway and the 7 coal pillar,the optimization of distance between the open-cuts of the 7 coal and 9 coal face,the optimization of the coal pillar width of the adjacent working face and the optimization of the replacement sequence of each working face.The purpose of all this methods was to achieve the prevention of rock outburst from the source.
