采掘工作面验证钻孔坍塌处理装置应用

基于煤矿大多采用复合指标法预测采掘工作面突出危险性的现状，给出了区域验证钻孔及测量仪器布置情况，分析了采掘工作面区域验证钻孔坍塌状态及影响因素，提出了一种以缓冲式挡煤器、高压风为主的处理装置。结果表明：该装置基于矿用CWY30型钻孔瓦斯涌出初速度测定器的结构设计，能够有效地处理被掩埋的仪器，减少了区域验证中测定仪器的损耗，降低了矿井瓦斯治理投入成本，消除了潜在的安全隐患，以保障现场施工人员的安全。

Practice of Veri fication of Drilling Collapse Treatment Device in Extractive Work Faces

Through the analysis of composite index method is used to predict coal mine mining working face of the status quo of outburst danger region tunnelling face verification borehole collapse buried the influence factors of measuring instruments, is proposed and developed a kind of to cushion block coal device, high pressure air processing unit. Type the device based on mine CWY30 borehole gas emission velocity meter structural design, can effectively handle buried instruments, reduce the wastage of the measuring instruments in the area to verify, reduces the mine gas control investment cost, eliminate the potential safety hazard, in order to protect the safety of site construction personnel.
