摘　　要：以西曲矿北二盘区8、9号煤近距离煤层动压影响下29205工作面正巷支护为实际工程背景,本文运用理论分析与矿压监测的研究方法,对29205工作面的合理支护参数进行了研究,并取得了良好的经济技术效果,保证了9号煤工作面安全高效的生产,对此类地质条件下下组煤回采巷道的支护设计具有有益的推广作用。This paper takes the geological condition of No. 8, No. 9 coal seams of 29205 working face pressure is under the influence of roadway support for practical engineering background, this paper using the method of theoretical analysis and mine pressure detection, the 29205 working face of the reasonable support parameters were studied, and achieved good economic and technical results. To ensure that the work of No. 9 coal production safety and high efficiency, is beneficial to promote the role of Coal Mining Group under such geological conditions of the roadway supporting design.
