摘要
本次边坡勘察通过钻探、室内试验及对滑坡的调查,初步分析一采区非工作帮滑坡是沿着19#煤层的风化带部位发生的;二采区排土场东北侧滑坡面(带)位于第四系表层与基岩全风化带部位,滑坡后缘陡坎和裂隙有向南西发展的趋势,存在再次滑动的隐患。
Through drilling, geotechnical tests and the investigation of landslide, the author analyzed that non-working slope in the first mining area was sliding along the weathering zone of No.19 coal seam. The northeast landslide in the second mining area dump was located in the quaternary surface and bedrock fully weathered zone. After landslide, edge scarp and crack has the development tendency from south to west, which exists the hidden sliding danger.
