Yaojie Coal Belt inclined shaft mine is located in Gansu province Lanzhou Honggu District kiln street town, mine to about 8.4Km long, sloping wide average of about0.8Km, well cropland area for2.99Km2. The main mining seam in No. 2coal mine, the average thickness of 27.41m, the simple geological conditions. Mine industrial reserves of 238216147t. Mine gas emission low, low gas mine. Mine for double shaft two level development, lane, using 3T bottom dump car coal, auxiliary transportation using 1t fixed Tramcar Transportation, mine ventilation for the parallel-type ventilation. The mine uses the inclined long wall fully mechanized top coal caving mining method. Mine year work on330D, time 16h net every day promotion. Mine working system using three eight, two production, a class prepared. 第一章 矿区概况及井田地质特征 第一节 矿区概况 一、井田位置、范围和交通条件 窑街煤电皮带斜井井田位于甘肃省兰州市红古区窑街镇，其地理坐标为东经102°53′03″，北纬36°24′42″。 井田走向长约8.4Km，倾斜宽平均约0.8Km，井田面积为2.99Km2。 窑街煤电集团公司三矿地处甘、青两省交界处甘肃侧，东距甘肃省兰州市120Km，西至青海省西宁市124Km。矿区内有专用铁路支线（海窑铁路），由铁运处集配站向南13.7Km到海石湾火车站与兰青铁路接轨；向北25Km经连城铝厂、连城电厂至西北铁合金厂；向东2.5Km到三矿选煤楼装车点。矿区公路向南17Km到海石湾与兰青公路相接；向北66Km至永登县与兰新公路衔接。铁路、公路交通运输十分便利。 窑街煤田交通位置图 图1-1 二、井田地形、地势 一）井田地形 皮带斜井井田展布于
