摘要
以莒山矿9号煤层充填工作面为研究对象,在综合分析开采地质条件的基础上,通过理论分析确定了支架的最大支护高度为2.1 m,最小支护高度为0.9 m,支护强度不低于0.443 MPa,确定了工作面中部和端头支架型号,为充填工作面支架选型和安全支护提供参考。
Based on the comprehensive analysis of mining geological conditions,the maximum support height of 2.1 m,the minimum support height of 0.9 m and the support strength of 0.443 MPa were determined through theoretical analysis,and the types of brackets in the middle and end of the working face were determined,which provide reference for the bracket selection and safe support of the filling working face.
