高压水射流卸压增透石门揭煤技术研究

Research on rock cross-cut coal uncovering via high-pressure water jet to release pressure and improve permeability

分析了高压水破坏煤岩机理,介绍了高压水射流割缝设备系统结构,该技术在首山一矿进行了应用,实现了石门安全高效揭煤,揭煤周期缩短了35.9%。

The mechanism of coal rock broken by high-pressure water was analyzed, and the system architecture of high-pressure water jet slotting equipment was introduced. The application to Shoushan No. 1 mine showed that this technique achieved the safe rock cross-out coal uncove- ring in high efficiency, and the period of coal uncovering was shortened by 35.9 %.
