摘要
矿山围岩的稳定性分级是矿山地下工程井巷支护设计和采场结构参数设计等工程基础数据,结合赤峰中色白音诺尔矿业有限公司现场调查资料及岩石力学试验数据,利用修正的BQ值进行围岩稳定性分级识别,综合考虑天然应力、地下水等因素,对矿山围岩进行工程质量分级和评判,确定围岩的稳定性,为矿山经济安全开采提供科学可靠的依据。
Stability classification of mine surrounding rock is the basic parameter of mine undergroun engineering,the supporting design of mine slope engineering and design of stope structure parameters. Combining with the filed exploration data of the Chifeng Baiyinnuoer Mining Co.,Ltd and experimental data of rock mechanics,the modified BQ value method is adopted to determine the stability of surrounding rock. The classification of surrounding rock quality and evaluation are conducted by considering natural stress,groundwater and other factors to determine the stability of surrounding rock and provide reliable scientific reference for taking economic and safe scheme of supporting and mining.
