摘要
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 actual topple mining and revolving mining of fully mechanized top coal caving face 10303 with higher mining height, research the movement characteristics of mining face surrounding rock and support stability through theoretical analysis and numerical simulation,proposed system control technology of preventing coal wall sloughing. The result was good through the on-site practice, it was realized smoothly caving.
