高瓦斯矿井复合顶板综放工作面支架选型

本文主要以山西兰花集团大阳煤矿三采区首个综放工作面为依据,通过类比法、经验法、理论计算法科学合理地对3303工作面进行了支架选型,针对工作面顶板、煤壁、初末采、断层、瓦斯及过陷落柱群等可能出现的问题提前采取应对措施,顺利通过了初次来压及X102,X101,X83陷落柱群及X98陷落柱和其伴生的F77正断层,并实现了瓦斯零超限,具有很好的推广意义。

Complex Roof Caving Face Support Selection and Safety Management of High Gas Coal Mine

This paper according to first fully mechanized top coal caving face of the three mining area of Shanxi Lanhua Group Dayang coal mine, using science and reasonable support selection by analogy method, experience method and scientific method the academic calculation in 3303 roof of working face, taken measures to the possible problems such as coal wall, the end of the early mining, fault, gas and collapse column group, successfully passed the initial pressure and X102, X101, X83 group and X98 subsided column collapse column with its associated F77 normal fault, realized zero gas overrun, it has very good popularization significance.
