摘要
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、理论计算法对3303工作面进行支架选型,分析综放工作面顶板管理的相应措施,顺利通过初次来压及X102、X101、X83、陷落柱群,为大阳煤矿其他采区及邻近矿井提供了借鉴经验。
On the basis of the first fully- mechanized mining face of No.3 mining area in Dayang Mine, analogy method, empirical method and theoretical method are used in the selection of supports and the analysis of the roof management for No.3303 working face. When the first pressure smoothly passing collapse column groups, X102, X101, and X83, the study provides some references for other mining areas in Dayang Mine and adjacent mines.
