Slipping-fall Mechanism and Control of Immediate Roof for Joint Rock Mass in Fully-mechanized Working Faces

根据现场实测和模拟实验结果，阐明了直接顶块裂岩体滑落冒顶的特征，建立了相应的力学模型，采用矢量计算法研究了块裂岩体稳定性及其控制参数。在此基础上，提出了控制滑落冒顶的技术措施。

Based on field observation and simulation tests,the characteristic of slipping-fall ofimmediate roof for joint rock mass is clarified,and a corresponding mechanical model is established in this paper.By the vectorial algebra method,the stability of joint rock mass and its control parameters are discussed.At last,the authors put forward technical measures to control the slipping-fall.
