摘要
针对神东公司寸草塔二矿的煤岩层地质特征,在该矿主斜井延伸段上下山巷道交岔点使用矿用U型钢棚+砌碹支护。通过理论分析表明矿用U型钢棚+砌碹支护在该矿使用是可行的、有效的,在实际应用过程中已取得了良好的效益。
According to the geological characteristics of coal and rock strata in Cuncaota №2 Coal Mine,the U-type steel and arching support was used in the roadway junction of extension section of main inclined shaft. The actual application has achieved good result.
