新密大磨岭煤矿采矿专项初步设计

摘要：本设计的井田面积约为16.4平方千米，设计开采煤层为二1煤；井田内煤层赋存比较稳定，煤层倾角7°－15°，平均倾角为11°,煤层平均厚度为厚4.92m，整体地质条件比较简单。该设计矿井为属高瓦斯矿井，涌水量较大，煤层不易自燃，具有爆炸性。

矿井设计年产量90万吨，矿井工作采用三八制；根据实际的地质资料情况进行井田开拓和准备方式的初步设计，该矿井决定采用立井一水平暗斜井二水平上山式开采，阶段内采用采区式划分，区段内设计采用综采放顶煤回采工艺，走向长壁采煤法，用全部跨落法处理采空区。

矿井采用抽出式通风，通风系统为两翼对角式，副井进风，回风大巷回风；井底车场选用立井刀式环形，井下主要运输选用采用矿车运输，并对矿井运输、矿井提升、矿井排水和矿井通风等各个生产系统的设备选型计算，以及对矿井安全技术措施和环境保护提出要求，完成整个矿井的初步设计。矿井基本实现机械化采煤，采用先进技术和借鉴已实现高产高效现代化矿井的经验，实现一矿一面高产高效矿井从而达到良好的经济效益和社会效益。

Western mining companies itwith him group is thriving coal mining special preliminary design

Abstract:the design for the field area is about 8.53675 square km, design for 2 1 coal mining coal; Within the occurrence compartmentalized is stable

and the coal seam 24 ° - 26 ° Angle for 25 °, average inclination thick coal seam thickness, average 5.88 m, whole geological condition is simple. The design of low gas mine as larger, coal mine, section, with explosive not spontaneous combustion.

90 million tons in the design of mine, mine production in 38 system; According to the actual situation of geological information compartmentalized exploration and ways to prepare the preliminary design, this mine shaft decided to adopt a level dark portal 2 level went up into the mountain type mining, stage by mining type partition, within section design using long-wall top coal caving in mining process, toward the longwall mining methods with all cross fell method, handle goaf.

By drawer-type ventilated, mine ventilation system for central boundary type, the boundary into wind, pregrouting wind Wells return air; Bottom of vertical annular wheel-dreven choose sword, downhole major transit transport, and choose to adopt harvesters mine transportation, mine ascension, coal mine drainage, and mine ventilation etc. Each production system, as well as calculation of equipment type selection of mine safety technical measures and environmental protection request, to complete the whole mine the preliminary design. Coal mine basic realize mechanization, the adoption of advanced technology and reference has realized high yield and high efficiency, realize the modernization of the experience of a mine mine mine a high yield and high efficiency to achieve good economic and

social benefits.

Keywords:

Actually, mining type preparation, toward the longwall, long-wall top coal caving, all the pieces fell method, drawer-type ventilated
