開采擾動下斷層構造區域沖擊地壓機理與防治技術(英文版) 內容簡介
本書在歸納分析近年來煤巖沖擊失穩問題研究方法的基礎上, 通過實驗研究、理論分析和現場實踐相結合的研究方法, 研究了采動影響下斷層活化過程和誘發沖擊地壓的機理。內容涉及開采過程中斷層應力狀態的演化規律, 開采活動導致斷層活化的機理以及斷層滑移瞬態過程煤體支承壓力的動態響應, 煤巖組合結構滑動變形破壞特征, 斷層失穩滑動的數學模型以及基于現場沖擊地壓事故案例分析的斷層影響下沖擊地壓發生規律、沖擊地壓多參量監測預警方法和解危措施等方面。

《開采擾動下斷層構造區域沖擊地壓機理與防治技術(英文版)》: 2.2.1 Experimental model and parameters The experimental prototype is 21221 fully mechanized caving face of coal seam 2# in Henan Yima coal mine.At the same time, it makes the general adjustment, so that the result of the experiment can be used for reference to the coal mine with similar coal seam condition.Experiments were designed to research the law of the rock pressure appearance and the migration and destruction of the surrounding rock in the dynamic process of the fault activation induced by mining activities during working face crossing fault in order to analyze the mechanism of the formation of fault rock burst. The geological land form of Yima coalfield is complex, and the area is hilly and gully.On the whole, Yima coalfield is a single syncline, which is bounded by faults.The segmentation of coalfield derivates a large number of strike and dip, oblique fault, fold and seam combination structure.The geological structure of Yima mining area is shown in Figure 2—1.The thick of directly roof of main mining 2—1, 2—3 coal in Yima coal mine is 0~24 m, which is covered with 180~410 m thick conglomerate.Under the influence of mining, the direct roof generally decreases with mining, while the thick conglomerate layer is not easy to break.The existence of the giant thick conglomerate is the difficulty to control the rock burst. ……
