基于10303大采高综放工作面回采受到仰采和旋转开采影响的实际,通过理论分析和数值模拟分析,研究了工作面围岩运动特征及支架稳定性,提出了系统的煤壁片帮控制技术。通过现场实践表明,应用效果良好。
Based on the fact that the working face recovery of 10303 fully mechanized caving mining face is influenced by vertical mining and rotary mining, the characteristics of the surrounding rock movement and the stability of the support are studied through theoretical analysis and numerical simulation. technology. Through field practice shows that the application of good results.
