深部厚顶煤巷道是深部开采工程中典型的难支护巷道，解决这一复杂问题控制围岩稳定性对煤矿安全生产具有重要意义。为探讨深部巷道围岩变形破坏机理，以巨野矿区赵楼煤矿为工程背景，开展了大型地质力学模型试验。研究了卸压锚箱梁系统支护围岩的位移和应力演化规律。同时，通过与现场试验的对比，验证和分析了围岩的主要破坏特征和破坏机理。(C)2015爱思唯尔有限公司版权所有。
The deep roadway with thick top coal is a typical roadway difficult to support in deep mining project, and resolving this sophisticated problem to control the stability of surrounding rock is of great significance in safety production of coal mines. In order to explore the surrounding rock deformation and failure mechanisms of such deep roadways, with Zhaolou coal mine in Juye mining area of China as the engineering background, a large-scale geomechanical model test was carried out. The displacement and stress evolution laws of surrounding rock supported by the pressure relief anchor box beam system were researched. Meanwhile, the related results validate and analyze main failure characteristics and mechanisms of the surrounding rock by comparing with field test. (C) 2015 Elsevier Ltd. All rights reserved.
