【正文】 an pan xie xie road west, direct from the southern area of railway huai aril, through the clever, Chen ~ by south road on the stage with clever, highway to more convenient traffic. Xieqiao coal Mt/a new Wells design. Located in huaibei plain xieqiao coal southwest, the transportation is convenient. Field to (for) the average length, field tendency (729 km south) average length for km, field level area for km2. This mine mining coal for 4 layer, in order to 1, from 4, 6 and 8, thick coal seam, m total % thick. The coal seam, the average for 8 % 176。 / m8, m 178。 hole mine ventilation easily. Before mine are chosen FBCDZ 8 late 28A. of twistaction axial fan motor, according to the power input and output power and main fan speed selection model for the requirements YR1 2508 of synchronous motor.Design content includes: (1) in ten chapter Outlines and field geological features, 2 laohutai mine field and reserves, 3 working system, the design of mine production ability and the service life, 4 field development, 5 to arrange tunnels, mining ways Mining methods。. The basic technical and economic indexes mine,This xieqiao coal mining design from the production practice, mines, design for large reserves of coal mining technology, design, development plan, and process of coal mine exploitation in China is very large, application of advanced technologies in China, is the main development direction of coal mining. In addition to the design results will not even coal mining ditch has certain directive significance, but also has similar conditions for the coal mining provides a very useful reference.Keywords: xieqiao coal, Three vertical shafts delay deep level dark, Mining ways to prepare, Comprehensive mechanized mining method, Wings diagonal type ventilation,6
