通过对山西西山晋兴能源有限责任公司斜沟煤矿18503综采工作面沿空留巷巷旁充填强度及留巷内支护强度设计进行研究,结合数值模拟,确定巷旁及留巷内的最优支护方式.同时,在留巷现场进行各项矿压观测,分析研究大采高综采面大断面沿空留巷的矿压显现特征,对大采高、大断面综采工作面沿空留巷效果进行综合评价,达到优化施工工艺及留巷支护参数的目的,为大采高、大断面综采工作面沿空留巷技术提供理论依据及实际经验.“,”The research of Xiegou Mine of Shanxi Xishan Jinxing Energy Corporation for oblique groove 18503 fully mechanized coal working face along the lane beside the filling strength and stay within the lane support strength design was studied,in combination with numerical simulation,the lane branch into the optimal support mode within the left lane was determined. At the same time,the scene of the left lane for the mine pressure observation,analysis and research for big mining height broken mining section along the characteristics of mine pressure appearance were made,the big cross section along the comprehensive evaluation of the effect for the fully mechanized coal face optimized the construction process and supporting parameters. The technology provided theoretical basis and practical experience for large broken mining height and the big cross section along the technology for the fully mechanized coal face.
