摘要
滨湖煤矿12202运输巷留巷中采用锚索梁支护方式,采煤时利用直接顶冒落矸石作为沿空留巷的充填材料,用工字钢棚作为巷内基本支护与巷内加强支护。矿压观测表明巷道支护状况良好,维护了巷道围岩的稳定性。
Anchor beam Supporting Technology was used in 12202 transportation roadway of Binhu coal mine, coal gangue caving from immediate roof coal was as filling materials of Gob Side Entry Retaining, I-steel shed was as primary supporting and strengthening support in the roadway. Underground pressure observation shows that the roadway support is in good condition, maintain the stability of surrounding rock of roadway.
