摘　　要：通过分析沿空掘巷时上覆岩层大结构的状态,说明了在沿空掘巷条件下维持巷道稳定的可能性及对小结构及时支护的必要性。对沿空掘巷时煤柱的留设问题进行了分析和计算。现场试验表明,通过合理地留设煤柱和对巷道围岩及时支护可有效保持巷道的稳定性,取得了良好的效果。By analyzing state of large structure of overlying strata,this paper believed that keeping roadway along gob which was driven along gob was possible and it was necessary for supporting small structure immediately.This paper analyzed and calculated width of coal pillar for driving roadway along gob.Actual test showed that rational pillar width and immediate supporting were favorable to keeping roadway stability.
