Discussion on maximum mining height of coal mining under water-containing condition in one mine field of northern Shaanxi province
摘要
Abstract
How to exploit coal resources under the premise of protecting the ecological diving, namely, the implementation of“coal mining under water-containing condition”, is a urgent technical problem to be solved in the construction of energy and chemical bases in Northern Shaanxi. Based on numerical simulation, taking a mine field in Northern Shaanxi as the research object, the growth regulation of wa-ter flowing fractured zone and the influence on ecological diving under different mining height were studied in this paper. The results show that the development height of water flowing fractured zone is mainly affected by the mining height. In order to realize the goal of “coal mining under wa-ter-containing condition”, slice and limit-height mining technology should be used in the study area. Based on this, the whole field is reasonably devided by limit mining height, which provides reference to ascertain the maximum mining height of slice mining.关键词
