摘要
根据孤岛工作面采空区上覆岩层受采动影响的程度,将其顶板结构分为全悬顶结构、半悬顶结构和完全移动结构。通过理论分析3种顶板结构的应力传递机制,建立了孤岛工作面支承压力估算模型,提出了支承压力估算方法,并构建了存在基于弹性承载区的孤岛工作面围岩整体失稳冲击危险性评估方法。采用本文提出的估算模型及评估方法,对"全悬顶-完全移动结构"和"全悬顶-全悬顶结构"孤岛工作面进行了冲击危险性判定,为矿山决策孤岛工作面能否安全开采提供了理论依据。
According to the mining influence level of the overlying strata above the gob of island coal face,its roof structures can be divided into fully hanging roof,semi-hanging roof and fully mining roof. By theoretically analyzing the stress transfer rule of the three types of roof structure,the calculation models of abutment pressure in the island coal face were set up,the calculation methods of abutment pressure were presented and also an evaluation method of rock burst hazard induced by overall instability of island coal face based on the existence of elastic loading zone was established in this study. The proposed calculation models and evaluation method were used to estimate the rock burst hazard of island coal faces with "wholly hanging roof-fully sedimentary roof"and "wholly hanging roof-wholly hanging roof",which provided a theoretical basis for the decision whether to mine island coal.
