安居煤矿1311工作面防冲治理措施及应用

Measures and Application of Preventing and Controlling Rockburst in 1311 Working Face of Anju Coal Mine

针对安居矿1311工作面冲击地压防治问题,采用减控措施、动态监测预警、强支护以及卸压孔卸压等措施,综合治理1311工作面冲击地压。采用顶板深孔爆破预卸压手段后,采掘期间矿震多以小能量为主,降低采掘过程中的矿震总能量以及大能量矿震问题,提高了低应力采掘环境,降低了工作面采掘期间的冲击地压风险,保证了工作面安全高效回采。

Aiming at the prevention and control of rock burst in the 1311 working face of Anju Coal Mine,measures such as reducing control measures,dynamic monitoring and early warning,strong support and pressure relief hole are adopted to comprehensively control rock burst in the 1311 working face.After adopting the pre-unloading method of roof deep-hole blasting,the mine earthquake is mainly small energy during mining,which reduces the total energy of mine earthquake and the problem of high-energy mine earthquake,improves the low-stress mining environment,reduces the risk of rock burst during mining the working face,and ensures the safe and efficient mining of the working face.
