摘要
针对陈四楼煤矿北翼F18断层与F13断层形成地堑采区复杂地质条件,通过合理留设采区边界断层防隔水煤柱,科学选择采煤方法,从工程量、投资及安全可靠性方面进行分析比较,确定采用利用现有北部东翼系统布置采区生产系统的最优方案,该方案工程量少、工期短、初期投资少,且有利于采掘接替,采区准备期间串联通风时间短、影响范围小,安全可靠性高,对矿井正常生产影响少,可为类似地质条件下的采区方案设计提供参考。
Aiming at the complex geological conditions of the graben block in the north wing of Chensilou Coal Mine,formed in F18 fault and F13 fault. Through reasonable arrangement of mining district boundary and water separation pillar,scientific selection of mining method,and after a detailed analysis and comparison of project quantity,investment,safety and reliability,the optimal scheme is determined,which uses the current system arrangement of production system in east wing of the north part,the proposed scheme has small project quantity and initial investment,short construction period and less influence on the normal mine production,which is conducive to the replacement of mining and development,and requires short period of series ventilation during primary mining.
