Abstract
in the coal mining area the erection of transmission lines exist great risk, how to correctly and objectively evaluate its impact, directly affect the line security and investment cost, this article from the start with the failure mechanism of coal mining area, thickness ratio method, the critical depth of mining empty area and the actual mining depth comparison method and probability integral calculation by using the method of mining in a transmission line, through the mining area and the future mine tower goaf stability is analyzed, the runtime verification, evaluation results are good, can learn from.关键词
