摘要
磁窑沟矿13号煤层下水平延深初步设计编制完成后,针对初步设计中原大巷利用、胶回暗斜井掘进坡度、盘区大巷层位选择、排水系统施工等方案设计不合理的情况,结合矿井工程施工经验,对方案进行优化改进。改进后的施工方案工艺简单,经济节约,实用性强,对类似条件矿井水平延深具有借鉴意义。
After the preliminary design of horizontal extension of No.13 coal seam in Ciyaogou Coal Mine is completed,in view of the unreasonable design of the original main roadway utilization,the driving slope of the rubber return concealed inclined shaft,the layer selection of the main roadway in the panel area,and the drainage system construction in the preliminary design,the scheme is optimized and improved in combination with the mine engineering construction experience.The improved construction scheme has the advantages of simple technology,economical economy and strong practicability,which can be used for reference for the horizontal extension of mines with similar conditions.
