摘 要:孤岛工作面作为煤矿开采中的一种特殊采掘形式,其矿压显性特征及分布规律的研究对安全生产至关重要,结合1017工作面展开细致的地质情况分析,并布置液压支架、应力计,采用数值模拟方法建模,对数据进行采集和分析。研究结果表明,液压支架工作阻力随推进距离表现出明显波动,不同支架在不同推进阶段压力变化规律明显。微震活动监测显示,矿压在回采过程中表现出周期性波动,高峰期和低谷期交替出现,矿压积累与释放过程动态平衡。通过对矿压进行监测与分析,能够为矿井安全措施的设计提供有利参考。As a unique mining form in coal mining,the study of ground pressure characteristics and distribution patterns in isolated island working faces is crucial for safe production.A detailed geological analysis of 1017 working face was conducted,hydraulic supports and stress meters were deployed,and numerical simulation methods were employed to model and analyze the collected data.The results showed that the working resistance of hydraulic supports exhibited significant fluctuations with the advancing distance,and the pressure variation patterns of different supports were distinct at different stages of advancement.Microseismic activity monitoring revealed that ground pressure exhibited periodic fluctuations during the mining process,with alternating peaks and troughs,indicating a dynamic balance between ground pressure accumulation and release.Through monitoring and analyzing ground pressure,valuable references can be provided for the design of mine safety measures.
