地面“L”型钻井瓦斯抽采设备与抽采管路系统优化探讨

针对淮南矿区高瓦斯、低透气性煤层群、煤岩松软、地质条件特别复杂的特点,采用地面"L"型钻井抽放瓦斯新技术,取得了较好的效果。随着顾桥矿"L"型钻井抽放瓦斯设备的选型成功,为今后实施地面钻井抽采瓦斯的抽放设备的选型优化以及类似矿井煤层抽采系统设计,均具有一定的借鉴作用。

L-surface Gas Drainage Drilling and Extraction Equipment Optimization of Pipeline System

For the features of low permeability and methane-rich seam group,quagginess of coalrock,complex geological condition in Huainan area,drilling gas drainage holes in "L" Shape from surface was adopted and worked well.The success selection of drilling implement will lend idea to the later designation of gas drainage system.
