针对采区准备巷道与回采巷道的有效联络方式,尤其是在斜巷的开采技术中,通过对采区中部车场多种联络方式进行技术、经济等多方面的分析,形成良好的联络方式与处理,并思考煤层的倾角、煤层间距之间的对应关系,在临界角度的分析中,找到最佳的联络方式,对于提升整个开采率有很大的帮助.“,”Based on effective contact way of preparation roadway and return roadway in mining area, especially in the mining of inclined lane, through the analysis of a variety of communication technology and the economic aspects of the formation in mining area, good communication and processing were made. Considering the corresponding relationship between coal seam dip angle and the coal seam spacing, the best way of contact was found during the critical angle analysis, which helped increasing the production rate.
