基于UWB通信的奇异点降噪分析冲击地压防治技术

针对集贤煤矿采煤过程冲击地压频发的实际情况,分析了3604工作面回采及收尾时发生动力现象的影响因素,结合采面生产的实际,运用钻屑法和电磁辐射法进行观测,确定3604工作面危险等级为三级。在此基础上,制定科学的防冲解危措施。结果表明:采取综合防冲措施后,钻屑法和电磁辐射法指标均在临界值以下,电磁辐射曲线变化幅度明显降低,矿压显现现象明显减少。关键词:冲击地压;采煤工作面;解危措施

Prevention technology of rock burst research and application

Aimed at frequent occurrence of rockburst in the Jixian coal operation,this paper offers an analysis of influencing factors associated with 3604 mining face and ending,and combined with the actual case of the mining face production,describes the use of cuttings method and electromagnetic radiation for observation in order to determine the hazard rate of 3604 face for three.The paper gives the scientific anti-the red solution measures.Results show that the use of comprehensive anti-red measures leaves the cuttings France and electromagnetic radiation indicators below the critical value,with a result of significantly reduced electromagnetic radiation curves and thus markedly reduced mine pressure behavior.
