摘　　要：以下沟煤矿ZF180 4综放工作面现场实测为基础 ,结合理论计算 ,得出采动影响条件下工作面超前支承压力范围 ,为两顺槽的端头支护提供了可靠的理论依据 ;同时通过实测与模型计算相结合 ,验算了区段煤柱留设尺寸的合理性 ,并在此基础上探讨了沿空掘巷无煤柱开采的可行性。Based on the field test and theoretical calculation of Face ZF1804 adopted longwall with top-coal caving mining,the paper presents the scope of abutment stress,which provides theoretical foundation for two-end supporting.Combined with field tests and numerical simulation,the size of section pillar is proved to be reasonable and the feasibility of driving without section pillar is also studied.

关 键 词：下沟煤矿 综放工作面 支承压力 煤柱 留设尺寸 沿空掘巷
