【摘要】 随着矿山开采规模的日益扩大,罗山矿区已经形成滑坡体Ⅰ,Ⅱ,Ⅲ,Ⅳ(体积约405.2×105 m3),严重制约着下方金、钼等多金属矿产资源的可持续安全开采。为能够对罗山矿区滑坡灾害进行超前预报,正确指导井下矿产资源的合理开采,首先,运用工程地质学、采矿学等理论分析罗山矿区滑坡体的形成机制,认为滑坡体松散-脆弱的地质结构和不合理采矿顺序是滑坡产生的主要原因,再加上降雨的催化作用加速滑坡的发生。其次,提出利用采矿治理滑坡的新思路,及时调整采矿顺序,从坡顶向坡脚开采,促使边坡向稳定方向发展。最后,以下滑力大于抗滑力是滑坡产生的充要条件作为滑坡体滑动的主要判据,应用滑坡远程监测预警系统在罗山矿区滑坡体上构建系统的滑坡体远程监测网。通过近10个月的现场试验,发现采用新的开采方案后,滑坡体朝着有利于边坡稳定的方向发展,从而证明采矿治理滑坡的科学性和可行性。更多还原

【Abstract】 With the scale extending of mining,the landslide in Luoshan mining area has became more and more serious(405.2×105 m3),which are being threatened to the sustainable safe mining of the underground mineral resources,such as molybdenum,gold and so on.First,in order to predict its landslide disaster early and guide the mining,the origin of Luoshan landslide is analyzed by utilizing the theories of mining and engineering geology.The results show that the weak geologic structure and unreasonable mining sequence and concentrated regional rainfall mainly caused those landslides.Then,a kind of new idea that uses mining theories to control landslide is put forward,and mining sequence is adjusted timely,which is from the slope top to the slope toe,making the slope more stability.Finally,based on the sliding criterion that sliding force is greater than the anti-sliding force is the necessary and sufficient conditions for occurrence of landslide,the principle and method for sliding force remote monitoring is presented;and a kind of systemic landslide remote monitoring network is established in Luoshan landslide mass.After 10-month site test,the landslide mass tends to be stable;and it shows that the method of using mining to control landslide is scientific and practical.更多还原
