新田煤矿副斜井揭煤技术实践研究

摘要

Xin Tian Coal Mine of Gui Zhou Province is characterized of complex regional geological structure, high gas pressure and content at the coal seam. In light of this real circumstance and relevant regulation, a series of practical outburst prevention measures and security work has been taken when auxiliary inclined shaft passing through No.4 coal seam, lead to sound prevention effect and safe coal uncovering, pre-senting certain reference for similar project construction.%贵州省新田煤矿区域地质构造复杂，煤层瓦斯压力和含量较大，在其副斜井井筒穿过4号煤层时，根据矿井的实际情况以及相关规程，制定了一系列切实可行的防突措施和安全防护工作，起到了良好的防突效果，安全完成了揭煤任务，对类似的工程施工具有一定的借鉴作用。
