摘要
在担水沟煤矿4203工作面,利用我国目前现有的监测设备,研究工作面围岩运动规律,分析冲击地压发生机理,开展冲击地压危险性程度评估,及时掌握冲击地压发展动态,确立冲击地压危险性预警指标。根据预警指标,及时对不同危险程度区域进行支护设计优化,全面提升矿井冲击地压治理能力。通过监测预警,进一步完善了防冲体系,消除了冲击地压灾害,为矿井的安全生产提供了有力的技术保障。
In No.4203 coal mining face of Danshuigou Mine,the present available monitoring equipment in China were applied to study the surrounding rock movement law in the coal mining face,to analyze the occurrence mechanism of the pressure bump,to conduct the risk degree assessment of the pressure bump,timely master the development trend of the pressure bump and to establish the risk early-warning index of the pressure bump.According to the early warning index,the support design optimization was timely conducted in the different risk degree areas and the control capacity of the mine pressure bump was fully improved.With the monitoring and early warning,the rockburst prevention system was further improved,the pressure bump disaster was eliminated and the strong technical guarantee could be provided to the mine safety production.
