摘要
基于济宁何岗煤矿勘探资料、采掘工程揭露资料及相关试验成果,采用实地调查、井下观测、统计分析等方法,对研究区采空区、冲击危险性、地下含水体等隐蔽致灾因素进行详细研究,查明了对矿井今后生产有影响的隐蔽致灾因素9项,可以排除的隐蔽致灾因素3项,结合各隐蔽致灾因素特征提出针对性防治措施.
Abstract
Based on the exploration data,mining and excavating engineering exposed data and related test results of Hegang Mine in Jining,the hidden disaster-causing factors including goaf,impact risk and underground water body in the study area were studied in detail by means of field investigation,underground observation and statistical analysis.Nine hidden disaster-causing factors affecting the future production of the mine were identified,three hidden disaster-causing factors of which could be excluded.Combined with the characteristics of each hidden disaster-causing factor,targeted prevention and control measures were proposed.
