磨儿田塌陷群位于四川沙湾区轸溪乡双山村,塌陷群从2004年开始出现第一个塌陷坑,到2012年在3 km2范围内共发育近20个大小不等的塌陷坑,最大塌陷坑直径超过30 m,深度达到65 m.严重威胁着塌陷区范围内10户共30人的生命财产安全.在现场调查分析的基础上,针对塌陷群的特征,通过对塌陷群成因机制、稳定性以及未来变形趋势分析,提出塌陷群的防治措施:遵循“以防为主,防治结合”的总体原则,以监测为主要手段,科学论证矿山的开采,辅以必要的搬迁和工程处理措施,可有效减少塌陷对村民的威胁.
The Sanda Collapse Group is located in Shuangshan Village, Zhenxi Township, Shawan District, Sichuan Province. The collapsed group has the first collapsed pit since 2004, and nearly 20 collapsed pits of different sizes have been developed within 3 km2 in 2012 with the largest The collapse pits are more than 30 m in diameter and 65 m in depth, which seriously threatens the life and property safety of 30 households in 30 subsidence areas. On the basis of investigation and analysis of the subsidence area, according to the characteristics of subsidence group, Stability and future deformation trend analysis, put forward prevention and cure measures of collapse group: follow the overall principle of “prevention first, prevention and control combination”, take monitoring as the main method, scientifically demonstrate the mining of mining, supplemented by the necessary relocation and engineering Measures can effectively reduce the threat of collapse to villagers.
