| 摘 要： | 安家岭煤矿存在大量不稳定块体,安全隐患非常高,必须进行关键块体的预防治理工作。以北帮1300边坡平台为工程背景,采用先进的三维岩体不接触测量技术,进行岩体结构面的现场测量,获取岩体节理几何形态空间分布信息,建立三维岩体结构面空间分布模型。在此基础上,利用获得的边坡岩体结构面基本参数信息,基于不稳定块体快速识别和分析系统(Geo SMA-3D),进行边坡关键块体的搜索,并对所得结果进行理论分析,确定边坡较易掉落的块体及影响块体不稳定的因素。

Digital recognition and key block identification of rock mass structure in Anjialing Coal Mine |
| |
| Abstract: | The rock masses are separated by structural surfaces and there are many instability blocks with different geometric shapes which can be easily seen from the field in Anjialing open pit.It is a high risk for the slope safety due to the bad geological condition，so a study on the blocks stability is urgently needed.In this study，the step at +1300 level of the slope was investigated.Firstly，the spatial geometric parameters of the structural planes was gained by photogrammetry using a three dimensional contact free measuring system.Then a 3D numerical model of the structural planes was built based on the measured parameters.Finally，a self developed software instability block fast recognition and analysis system (GeoSMA 3D) was used to search and analyze the key block of the slope rock mass.The simulation results reflect the actual situation very well，which means that the method of the key block search and analysis is reasonable and feasible. |
