库兹巴斯的托姆—乌申斯克地区矿区地质条件的特点,是在局部地带煤层直接顶赋存有大量后生成的冲蚀岩石。这些地带为中等难冒落的粗粒至细粒粉砂岩,岩石抗压强度为30～70MPa,厚达12m,作
The characteristic of the geological conditions in the Tom-Usinsk area of Kuzbass is that a large amount of post-formed erosion rock is deposited directly on top of the coal seam in local areas. These areas are coarse-grained to fine-grained siltstones that are hard to fall off, with compressive strength of 30-70 MPa and thickness of 12 m
