某矿11301工作面冲击危险性分析

Risk analysis on Rock Burst of 11301# working face in one mine

中文摘要英文摘要

某矿开采深度达到900m左右,属深部开采矿井,11301工作面掘进期间即有冲击动压显现,其中的2次底板冲击较为强烈,而目前对顶板冲击矿压的研究较少。利用FLAC3D数值模拟软件模拟了11301工作面开采过程中的应力演化规律,并划分了重点防冲区域,提出了11301工作面在开采期间需要采取的巷道底板卸压等几项防冲措施。所得结论对具有类似条件冲击危险矿井的冲击矿压防治工作有一定指导意义。

he mining depth of one Coal Mine reaches 900m. There were rock and coal dynamic events in the roadway drivage of the first 11301# working face,especially 2 of which were relatively strong floor rock bursts. However there has been little study about floor rock burst at president.Using the FLAC3D numerical simulation software to simulate the law of stress evolution in the process of 11301 working face production.The key areas of rock burst prevention were defined and finally the rock burst prevention measures during mining, such as relieving-shot in the floor of roadway, were presented. The conclusions in this paper have some guiding significances for the rock burst prevention in those deep mines with similar conditions and rock burst danger.
