摘　　要：为了实现对大同煤矿集团四台矿保安煤柱的安全复采,针对残采区保安煤柱复采工作面沿空巷道围岩的具体情况,提出了一套合理的支护方案,并确定了具体的支护参数。现场实测表明,该支护方案对沿空巷道支护效果显著,为类似残采区煤柱复采提供了一定的借鉴。In order to realize the safe re-mining of the security coal pillars of Sitai Coal Mine of Datong Coal Mine Group,this paper proposed a reasonable supporting scheme based on the conditions of the surrounding rock of gob-side entry in security coal pillar re-mining face in residual mining area and determined the specific supporting parameters.Field measurements indicate that the support scheme has a significant effect on the support of gob-side entry,and provides a reference for the coal pillars re-mining in the similar residual mining area.
