基于Sirovision节理岩体调查及岩体质量分级与支护研究

Joint Rock Mass Survey and Rock Mass Quality Classification and Support Research Based on Sirovision

针对传统岩体结构信息测量方法工作效率低、岩体结构信息不准确、劳动强度大、危险系数大等问题,利用Sirovision岩石三维遥感测量系统对岩体结构面信息进行了测量分析。以沂南金矿-540中段左叉穿巷为工程背景,进行岩体结构面调查和岩体结构面数字化识别,对岩体结构面的产状、产状分布规律、优势节理等进行分析,并根据岩石RMR和Q分级方法对-540中段岩体质量分级。综合分析得到该区域岩体为Ⅲ级一般岩体的结论,并根据岩体分级结果对该区域提出相应支护方案,通过数值模拟结果发现,该支护方案可将巷道顶板位移量控制在100 mm范围内,提高了支护效率,对矿山安全生产起到了积极作用。

Aiming at the problems of low efficiency and high labor intensity and high risk coefficient of the traditional measurement method of rock mass structure information,the information of rock mass discontinuity was measured and analyzed by using Sirovision rock 3D remote sensing measurement system.Taking the left fork tunnel in the middle section of-540 in Yinan gold mine as the engineering background,the investigation and digital identification of rock mass discontinuities were carried out,and the occurrence,distribution law and dominant joints of the rock mass discontinuities were analyzed,and the rock mass quality of the middle section of-540 was classified according to the rock RMR and Q classification methods.Based on the comprehensive analysis,it is concluded that the rock mass in this region is general rock mass ofⅢgrade.According to the classification results of rock mass,the corresponding support scheme is proposed for this region.Through the numerical simulation results,it is found that the support scheme can control the displacement of roadway roof within the range of 100 mm and improves the support efficiency and plays a positive role in mine safety production.
