一种多灾元耦合难采煤层解耦开采方法
摘要：
本发明公开了一种多灾元耦合难采煤层解耦开采方法，基于复杂难采煤层类型及灾元类型，分析多灾元致灾因素相互耦合关系与构成比重，建立不同灾元致灾贡献度评价方法与指标体系；通过计算各灾元的危险性指数及开采活动中不同灾元致灾贡献度，能够确定主导灾元、其它致灾因素排序、不同灾元间耦合层级与顺序；确定了多灾元耦合难采煤层整体和局部解耦顺序；然后，以开采为核心，提出了解耦方法；依照解耦层级和顺序、灾元间相互作用关系，简单化了治理矿井灾害的目标，在矿区规划、建设和生产等主要阶段，解耦灾元，降低耦合程度，最终消除矿井灾害，进而提高矿井生产安全性。
摘要（英）：

The invention discloses a multi-disaster-element coupling hard-to-mine coal seam decoupling mining method. Based on the types of a complex hard-to-mine coal seam and disaster elements, the intercoupling relation and composition proportion of multi-disaster-element disaster-causing factors are analyzed, and a disaster-causing contribution degree evaluation method and index system for different disaster elements are established; by calculating the risk index of each disaster element and the disaster-causing contribution degrees of the different disaster elements in the mining activity, a dominant disaster element, other disaster-causing factor ordering, the coupling level and order among the different disaster elements can be determined; the overall and local decoupling order of a multi-disaster-element coupling hard-to-mine coal seam is determined; and then the decoupling method is provided with mining as the core. According to the decoupling level and order and the interaction relationamong the disaster elements, the target of treating the mine disasters is simplified, in the main stages of mine planning, construction, production and the like, the disaster elements are decoupled,the coupling degree is reduced, the mine disasters are eliminated finally, and thus mine production safety is improved.
