基于浮力定理的煤矿防冲研究与应用

Research and application of rock-burst prevention and control technology based on Buoyancy theorem

星村煤矿为极复杂地质条件超千米深井,防冲工作为重中之重,研究冲击地压发生的机理,从而进行防冲治理迫在眉睫。通过对浮力定理的扩展,深刻理解煤矿防冲中的难点,并加以运用,收到了较好的效果。

Xingcun coal mine has very omplicated geologic conditions,its burial depth is over 1000 m,the work of the rock- burst prevention and control is the priority among priorities,studying on the mechanism of rock- burst,and taking prevention and control measurement are very imminent. By extending and using the principle of buoyancy,received the good effect.
