复煤层分层回采和煤层群联合采掘过程中,经常发现两类特殊的断裂现象:一类小型断层仅发育在塑性较强的煤层及泥质岩类中,其垂直断距由0.1米—1.0米,沿走向延伸长度由数十米至万余米。沿断层面倾斜方向被限定于塑性较弱的岩层之间。(图1)这类微型隐伏
Two types of special faults are often found in the process of stratified mining of double-layer coal seams and joint mining of coal seams: one type of small faults is only developed in coal and muddy rocks with strong plasticity. The vertical fault offsets are from 0.1 m -1.0 Meters, extending along the length of tens of meters to ten thousand meters. Tilt direction along the fault plane is limited to between the less plastic formations. (Figure 1) This type of miniature hidden
