黄陵矿业一号煤矿围岩控制支护技术研究

Research of surrounding rock support technology in Huangling No.1 coal mine

以西安科技大学黄庆享教授提出的自稳隐形拱理论为基础,通过计算得出黄陵矿业一号煤矿六盘区回采巷道围岩控制支护参数。选取六盘区625进风顺槽作为试验对象,采取多元化矿压观测方法,对试验区域受一次采动影响进行现场观测、记录、分析;受二次采动影响采用数值模拟分析,得出动压巷道受两次采动影响后的围岩活动规律。同时运用计算机数值模拟软件分布多次迭代计算方法测定巷道围岩松动圈,来指导一号煤矿回采巷道支护的科学设计。

Based on the theory of self-stabilized invisible arch,the support parameters of mining roadways in sixth panel of Huangling No.1 Coal Mine were calculated.Taking No.625 mining roadway in sixth panel as research object,the field observation and analysis of the influence of first mining were carried out by means of diversified mine pressure observation method,the influence of secondary mining was analyzed by numerical simulation,and the surrounding rock movement law of mining roadway affected by twice mining was obtained.At the same time,the loose circle of roadway surrounding rock was calculated by numerical simulation software,which can provide guiding for scientific and rational design of the support parameters for the mining roadway in Huangling No.1 coal mine.
