    Comprehensive Monitoring and Prevention Technology of Rock Burst in a Thousand Meters Deep Mine

    • 摘要: 为了解决千米深井工作面开采引起的局部应力集中与冲击危险防治问题,提出了“采前危险区划定-预卸压-冲击危险综合监测-加强支护-卸压解危-效果检验”的冲击矿压综合监测防治体系:采用多因素耦合法对工作面区域进行采前危险性分析并进行预卸压处理;随工作面回采,通过“实时监测-中期监测-长期监测”+“区域监测-局部监测-点监测(检验)”的动态多尺度监测方法对冲击危险区危险性进行监测和检验;确定冲击危险后,进行加强支护、卸压解危和效果检验,直至冲击危险解除。该体系在星村煤矿E3207工作面进行了应用,采前和采中分别精确监测到工作面轨道巷32°转弯点区域存在应力集中并存在强冲击危险,及时进行解危处理。

       

      Abstract: In order to solve the problem of stress concentration and rock burst hazards resulted from work face mining in a thousand meters deep coal mine, this paper proposes a comprehensive monitoring and prevention technology system of “dividing risk areas before mining+pressure relief in advance+comprehensive monitoring+strengthening support+releasing stress to eliminate risk+testing the effect”; the multi-factor coupling method was used to analyze the pre-mining risk in the working face area and carry out the pre-unloading treatment; with the mining of work face, using the dynamic multi-scale monitoring method of “real-time monitoring+medium-term monitoring+long-term monitoring” and “regional monitoring+ local monitoring + point monitoring” to monitor and test the danger in the impact danger area; after determining the rock burst risk, measures of strengthening the support, releasing stress and testing effect are taken and the impact risk is relieved. This system is used in identifying stress concentration area of E3207 face track lane 32° corner point area before and during the mining in Xingcun Coal Mine and immediate pressure relief has taken.
