摘要
2009年朱村矿使用高档普采设备,回采1.0～1.4M的薄煤层,利用膏体充填法充填采空区,工作面单产比炮采工作面提高了3倍以上,摸索出了薄煤层中采用机械化绿色开采的新技术,为资源枯竭的矿井开辟了新的发展之路。
The use of high - grade conventional mining equipment in 2009 in Zhucun Coal Mine, mining 1. 0- 1.4M thin coal seam, using the paste filling method to filling mined -out area, made the output in- creased as more than 3 times as the blasting mining face.
