摘要
在系统总结采矿工程与其他岩土工程相互关系的基础上,从煤矿地下巷道的空间几何特征、围岩介质特征、采动影响特征和技术经济特征等4个层面,全面分析了大采深煤矿地下巷道的工程特性。重点论述了大采深地下巷道周围应力重新分布规律的特点和受回采工作采动影响的回采巷道的围岩变形发展变化过程,阐明了学科交叉与技术交流的重要性。
On the basis of systematically summarizing the relationship between mining engineering and other geotechnical engineering,the project characteristics of underground coal mine roadway in deep mining are analyzed comprehensively from four aspects such as space geometry,surrounding rock features,impact characteristics of mining and technical and economic characteristics etc..The stress re-distribution characteristics around the underground roadway in deep mining and the development process of roadway surrounding rock deformation affected by mining work are discussed emphatically,and the importance of interdisciplinary and technology communication are clarified.
