针对六家煤矿极近距离煤层群回采巷道变形严重、支护困难等问题,采用理论分析、现场监测等研究手段,对 SIIS16－7工作面运输巷道矿压进行监测与分析.研究表明：巷道两帮及顶底板围岩松软,受到采动影响围岩破碎严重,支承压力升高,巷道支护困难；现场实测巷道两帮最大移近量0.56 m,顶底板最大移近量0.42 m,故现有支护存在不足,需对原有的梯形架棚进行二次补强支护.

Aimed at the serious deformation and hard supporting of mining roadway in ex-tremely short-distance coal seams of Liujia Coal Mine,the theoretical analysis and field monito-ring were adopted to analyse the rock pressure in the haulage way of SIIS1 6-7 working face. The research results showed that the surrounding rocks of roadway's sides and roof and floor were soft,which had been broken seriously influenced by mining,the support pressure rose so that the roadway support was very difficult. According to the field measurement,the largest amount of deformation between roadway's sides was 0.5 6 m,and the largest amount of deformation between roof and floor was 0.42 m,so the existing support measures had shortcomings,the original trap-ezoidal frame sheds should be reinforced once more.
