摘要
为了进一步认识水平分层综放开采的开采沉陷特点,运用相似材料模型实验,对某矿大倾角煤层的开采沉陷过程进行了模拟研究,揭示了急倾斜特厚煤层水平分层深部开采岩层与地表移动规律.
The subsidence characteristics of horizontally-sliced mechanized top-caving mining are different from those of either flat seam mining or steep-inclined middle-thick seam mining. Similar material model test was used to simulate the rock mass movement of steep-inclined super-thick coal seam of a coal mine. The results revealed the law of strata movement and ground deformation due to horizontally-sliced mechanized top-caving mining at a greater depth of steeply-inclined seam, which would provide a guide to real mining.
