厚硬顶板破断诱发矿震机制及减震技术
Mechanism of mine seismicity induced by thick and hard roof failure and mitigation techniques
摘要
Abstract
In order to investigate the factors inducing mine seismicity and reduce the frequency and degree of mine seismicity,this study focuses a coal mine in the Ordos region.By integrating field evaluation,theoretical analysis,scheme design,in-situ measurement,and industrial-scale testing,the mechanism of mining-induced seismicity triggered by thick-hard roof fracture was analyzed,and a cooperative pressure-relief and seismicity-reduction technology combining"hydraulic fracturing in roadway roof,directional long-hole hydraulic fracturing,and surface deep-hole blasting"was proposed.The research results show that the inducing factors of mining-induced seismicity in thick-hard roof working faces include mining depth,geological structures,lithological variations,advance rate,periodic weighting,etc.When multiple factors overlap,the frequency of mining-induced seismicity increases significantly.After implementing the pressure-relief technology,the average periodic weighting interval of the working face was reduced from 17.32 m to 14.81 m,a decrease of 14.49%.The monthly frequency of microseismic events increased from 185 to 1 902,with small-energy microseismic events accounting for 73.2%,exhibiting a"high-frequency,low-energy"distribution pattern.The pressure-relief and seismicity-reduction technology demonstrated excellent effectiveness,significantly lowering the risk level of mining-induced seismicity.The research conclusions provide a reference for mine earthquake control under similar conditions.关键词
