一、概况 淄博矿区现有的九个矿井中,薄煤层产量占80％,0.8米以下的极薄煤层产量占35％以上。矿区内可采煤层和局部可采煤层共十余层,煤层平均厚度不到1米,平均生产能力只有1.3吨/米~2,而且煤层的伪顶、断层多,开采条件极为复杂。 过去,采区多采用盘区布置,沿煤层倾斜开上下山,顺槽沿走向布置,矿车进采区溜头接车运输。这种布置方式存在着采区分散,生产能力低,运输卡脖子等弱点,致使
I. Overview Zibo mining existing nine mines, thin seam production accounted for 80%, 0.8 m below the production of very thin coal seam accounted for more than 35%. In the mining area, there are more than ten layers of recoverable seams and local recoverable seams. The average thickness of coal seams is less than 1 meter and the average production capacity is only 1.3 tons / m ~ 2. Moreover, there are many false tops and faults in coal seams and the mining conditions are extremely complicated. In the past, the mining area to use more panel layout, along the seam slope up and down the mountain along the slot layout, the car into the mining area skidding car transport. This arrangement exists in mining area scattered, low production capacity, shipping cards neck and other weaknesses, resulting in
