【摘要】 煤与瓦斯突出、冲击地压和矿震统称为矿井动力灾害,是煤矿中的主要动力灾害。平顶山矿区随着开采深度的增加,开采中以煤与瓦斯突出等矿井动力灾害强度上加剧,频度上提高,对深部煤炭的安全高效开采造成了巨大威胁。本文以平顶山东部矿区的八矿、十矿、十二矿为研究基地,针对煤与瓦斯突出等矿井动力灾害的预测预防技术进行了研究。确定了平顶山东部矿区煤与瓦斯突出动力系统的临界能量,建立了评价矿井动力灾害的动力环境的方法,得出平顶山矿区煤与瓦斯突出和天然地震在时间、空间、强度上存在阶段相关性。综合考虑褶曲、断层、构造煤及煤层瓦斯等多因素影响,构造应力、瓦斯压力与采动应力相互耦合,煤岩固体骨架变形与孔隙压力变化的相互制约关系,揭示了平顶山矿区深井动力灾害多因素耦合统一灾变机理,建立了统一数学模型。提出了基于地质动力区划的深井动力灾害统一预测理论,建立了深井动力灾害统一预测的模式识别概率预测方法,实现了深井动力灾害从单因素预测向多因素预测发展、从点预测向区域预测发展、从定性预测向定量预测发展。开辟了深井动力灾害预测研究的新领域,建立了一个比较科学的深井动力灾害预测方法。提出了弹性能量速度指数、冲击能量速度指数两个新的冲击倾向性测试指标;发展了深井动力灾害钻屑温度法、电荷法、煤体应力法统一监测预警技术;研制了钻屑温度测试装置、钻孔温度监测装置、电荷传感器和在线式电荷监测系统,确定了监测敏感指标;研发了一套深井动力灾害统一监测预警系统;建立了平顶山矿区深井动力灾害危险性评价与预测技术指标体系。提出了适合平顶山东部矿区,以水驱气、水力压裂、深孔卸压爆破为主的深井动力灾害统一防治技术,并制定了操作规程。

【Abstract】 Coal and gas outburst, rockburst and mining-induced seismicity collectivelyreferred to as the dynamic disasters is the main driving force in the coal mine disaster.Pingdingshan coal mine with the increase of mining depth, coal and gas outburstdynamic disasters intensity increased, the frequency increase, poses a significantthreat to the safe and efficient mining of deep coal. Take Mine No.8, No.10and No.12in the east of Pingdingshan coal mine as the research base for coal and gas outburstdynamic disasters prediction and prevention.Determined the critical energy of coal and gas outburst power system in the eastof Pingdingshan coal mine, established evaluation method of the dynamicenvironment of the mine dynamic disasters, drawn coal and gas outburst and naturalearthquakes in on time, space, strength phase in Pingdingshan Coal Mine. Consideredfolds, faults, tectonically deformed coals and coal seam gas factors, tectonic stress,gas pressure and mining pressure coupled with each other, the solid skeleton of coalor rock deformation and pore pressure changes in each other restrictive relationship,revealed deep mine dynamic disasters multi-factors coupling unified disastermechanism in Pingdingshan coal mine, established a unified mathematical model.Proposed unified prediction theory of deep mine dynamic disasters based ongeodynamic zoning, established a deep mine dynamic disasters uniform predictablepattern recognition probability prediction methods, deep mine dynamic disasters fromthe single factor forecast to predict the development of multi-factor forecast to predictthe development to the region from the point from the qualitative prediction toquantitative prediction of development. Opened up new areas of the deep minedynamic disasters prediction, established a scientific deep mine dynamic disastersprediction method. Elastic two new rockburst preference test indicators, energyvelocity index and rockburst energy speed index; developed a deep mine dynamicdisasters unified monitoring and warning technology,include cuttings temperaturemethod, Charge method and coal stress method; developed cuttings temperaturetesting device, borehole temperature monitoring device, charge sensor and on-linecharge monitoring system, determined monitoring sensitive indicators; developed adeep mine dynamic disasters unified monitoring and warning system; establisheddeep mine dynamic disasters assessment and prediction techniques index system inPingdingshan coal mine.Developed a set of deep mine dynamic disasters unified prevention techniques for Pingdingshan coal mine, including hydraulic fracturing, water-drive gas technology,deep hole blasting technology, etc.; Prepared deep mine dynamic disasters unifiedprediction and prevention technical regulations for Pingdingshan coal mine.
