平顶山矿区深部动力灾害防治与资源绿色开采

Prevention and control of deep dynamic disasters and resources green exploitation in Pingdingshan Mining Area

  • 摘要: 中国平煤神马集团开采的平顶山矿区是我国煤矿深部开采的典型代表,历经70 a的发展,集团始终坚持以科技力量引领生产,以技术装备保障安全,对瓦斯的认识不断深化,走过了“被动防、主动治、绿色用”三大阶段,动力灾害监测预警技术能够超前研判灾害发生概率,预测不发生动力灾害准确率达到100%,发生动力灾害准确率达80%,使瓦斯灾害可防可控;低渗煤层瓦斯的高效增透抽采技术使瓦斯治理周期由24个月缩至8个月,吨煤瓦斯治理成本降低了60%;瓦斯“抽采—发电—制冷”一体化绿色开发利用技术有效降低巷道温度5~10 ℃,瓦斯抽采浓度提升到50%,保障了矿井冬季取暖和夏季制冷,日均节省用电消耗6万kW·h,既消除了瓦斯威胁,使矿井瓦斯变害为宝,又保障国家煤炭供应安全,符合“双碳”目标的发展需求。未来,集团将以深部动力灾害的防治为基础,积极推进煤炭转型绿色利用,构建以炼焦煤资源安全开采、高效分选、绿色转化的产业化道路,推进企业快速转型升级,打造领跑行业的科研创新平台,保障国家能源供应安全、紧跟社会经济发展步伐。

     

    Abstract: The Pingdingshan mining area mined by China Pingmei Shenma Group is a typical example of deep mining. After 70 years of development, the group always insists on leading production with scientific and technological strength, ensuring safety with technical equipment, deepening its understanding of gas, and has gone through three stages of “passive prevention, active treatment and green use”. The monitoring and warning technology of dynamic disaster can predict the probability of disaster occurrence in advance, and the accuracy of predicting no dynamic disaster can reach 100%. The accuracy rate of power disaster is 80%, so that gas disaster can be prevented and controlled; The efficient anti-reflection extraction technology of gas in low-permeability coal seam reduces the gas treatment cycle from 24 months to 8 months, and the cost of gas treatment for tons of coal is reduced by 60%. The integrated green development and utilization technology of gas “extraction – power generation – refrigeration” can effectively reduce the roadway temperature by 5–10 ℃, increase the gas extraction concentration to 50%, guarantee the mine heating in winter and refrigeration in summer, save 60 000 kW·h of electricity consumption per day, not only eliminate the gas threat, make the mine gas become treasure, but also ensure the national coal supply security. Meet the development needs of the “double carbon” goal. In the future, based on the prevention and control of deep dynamic disasters, the group will actively promote the green utilization of coal transformation, build an industrialization road of safe mining, efficient washing and green transformation of coking coal resources, promote the rapid transformation and upgrading of enterprises, build a leading scientific research and innovation platform in the industry, ensure the security of national energy supply and keep up with the pace of social and economic development.
