摘    要:针对综放开采煤壁前方支承压力的分布特征,应用统计损伤力学建立了一个简单的力学模型,在给定变形条件下研究支承压力的分布规律,避免了对支承压力的分区研究,理论结果和实验结果具有很好的一致性,最后对支承压力的影响因素,加以讨论。

关 键 词:支承压力  综放采场  损伤力学  矿业

Abstract:Based on the abutment pressure distribution around a coal face, a simple damage mechanics model is used to discuss the distribution pattern of abutment pressure under the condition of confined deformation. It is not needed to zone the range of the abutment pressure (limited equilibrium zone and elastic deformation zone) with this model. The theoretical results are agreeable with the experimental results. Finally, some factors to affect the distribution pattern of the abutment pressure are discussed, such as the strength and thickness of coal, in situ stress.
Keywords:abutment pressure  top coal caving around a coal face  damage mechanics
