Abstract
In order to effectively solve the problem of severe dynamic pressure deformation in the goaf roadway of Jingfu Company,based on the roof breaking structure characteristics of the goaf roadway,the coupling blasting with high-strength water-gel explosive and special shaped charge pipe is put forward,which can improve the directional effect of gas,increase the damage effect of blasting on surrounding rock,and improve the depth of deep-hole rock-breaking and directional pre-splitting effect.The key technical parameters of water-gel explosive lateral blasting roof-cutting are determined according to the roof-breaking structure characteristics of 15#goaf roadway in Jingfu Company,forming a complete set of lateral blasting roof-cutting technology system to prevent and control the dynamic pressure of goaf roadway.The results show that the tech-nology can effectively control the deformation of the roadway,solve the problem that the deformation of the roadway is seri-ously affected by the mining of the adjacent working face,reduce the cost of roadway support,and ensure the safe and effi-cient production,increased economic benefits.关键词
