摘　　要：沿空掘巷技术的关键问题是掘巷位置和掘巷滞后时间,针对106煤矿的11采区沿空掘巷的具体问题,在分析侧向支承压力分布特征的基础上,确定留设小煤柱宽度为5 m。根据部分矿井以往的经验数据,沿空掘巷滞后上区段回采的合理时间为6个月。The key problems of gob-side entry driving technology are roadway position and lag time; aim at the specific problems of gob-side entry driving in the 11 mining area of 106 coal mine, based on analyses of distributive characteristic of side abutment pressure, it is confirmed that the width of small coal pillar is 5 m. According to the previous empirical data in some coal mine,the reasonable time is 6 months that the gob-side entry driving is delayed for 6 months after finishing the last section mining. Joining actual application.

关 键 词：沿空掘巷 掘巷位置 侧向支承压力 滞后时间
