提出了一种新的石门揭煤的工艺,即将揭煤巷道的1段密封住,并注入一定压力的空气,以解决石门揭煤过程中存在的周期过长,安全性差的问题。针对该工艺中的几个关键问题,通过实验室实验和现场试验进行了分析说明,结果表明:该工艺可以取得较好的安全效果,达到有效防止突出的目的。 A new technology of exposing coal in Shimen was put forward, that is to say, sealing the first stage of the coal roadway and injecting the air with a certain pressure so as to solve the problem of the long period and poor safety in the process of exposing the stone door. Aiming at several key problems in the process, the laboratory experiments and field tests are conducted to illustrate the results. The results show that the process can achieve better safety results and achieve the purpose of effectively preventing the problems.
