摘要
针对我国浅埋厚煤层采场顶板失稳导致的压架事故频发等顶板致灾问题,在分析浅埋煤层顶板赋存条件、破断失稳特征及结构类型的基础上,根据顶板的致灾类型和特征,建立了顶板失稳致灾监测预警模型,确定了监测内容和预警指标,并在现场进行了应用,取得了良好的效果。
According to the roof occurrence and production conditions of shallow thick seam exploitation, together with the frequent crushing disasters during the period of the pressure change of working face in west China, analyzed the occurrence conditions, breaking insatiability features and structure types of shallow thick seam. Based on the types and features of roof disasters, it built the forewarning model of the accident of roof instability, and determined the monitoring contents and the warning indexes. It achieved good results through field application.
