冲击危险采区防冲优化设计探讨

Discussion on optimal design of prevention rockburst in mining area with Rock Burst Hazard

很多冲击地压事故发生的主要是由于开采设计不合理引起的,不合理的巷道布置及开采顺序将会形成高应力集中区,对后期的冲击地压防治及安全生产造成隐患;冲击危险区域煤炭的安全开采应从设计源头做起,最大限度降低或避免人为形成的高应力集中条件。本文针对东滩煤矿十四采区西部区域的安全开采问题进行了防冲优化设计,为采区后期的冲击防治工作打下了基础。

A lot of rockburst accident is mainly caused by unreasonable exploitation of design, unreasonable roadway layout and mining sequence which will be form the high stress concentration zone, and form the hidden danger of rock burst for later prevention and safety production; the prevention rockburst in area with rock burst hazard should be done from an design source, to minimize or avoid high stress of anthropogenic concentration conditions. aiming at the problem of safe mining in the fourteen western mining area of Dongtan coal mine,put forward the optimization design preventing rock burst, and laid the foundation for prevention rock burst later.
