石门揭煤是防突工作中的重要内容,而防突工艺更是实现其高效、安全的前提。针对传统石门揭煤技术的不足,结合松河矿井的具体情况,提出了一套完整的石门揭煤防突工艺,并分析了应用效果,实现了安全快速揭煤,为其它类似条件下高瓦斯煤层群石门揭煤提供了较好的参考。 Shimen exposed coal is an important part of anti-sudden work, and anti-sudden process is to achieve its efficient and safe premise. In view of the shortcomings of the traditional crosscut coal uncovering technology and combined with the specific conditions of Songhe coal mine, a complete set of outburst prevention technology for crosscutting coal in Shimen was put forward. The application effect was analyzed and a safe and fast uncovering of coal was realized. For the other similar conditions, Coal seam group crosscut coal door provides a good reference.
