深井巷道维护费与采深的关系

RELATIONS BETWEEN THE MAINTENANCE COST OF ROADWAYS AND MINING DEPTH IN DEEP COLLIERY

根据巷道维修记录，采用统计分析方法，找出了孙村矿实际发生的开拓和准备巷道维护费与采深的关系，讨论了巷道维护费的变化特点，指出，改革巷道布置模式和通过开采改变开采边界条件是减少深井深部开拓和准备巷道维护费的主要途径．

According to the records of roadway maintenance,and using statistical analysis method, the relation is found out between the real maintenance cost of development and preparation roadways and mining depth in Suncun Colliery, the changing features of the roadway maintenance cost is discussed. It is shown that to reform roadway layout pattern and to change mining boundary condition by mining is the main way to reduce the maintenance cost of development and preparation roadways in the deep mining of deep colliery.
