摘要
Abstract
In order to solve the causes and mechanisms of coal rock erosion caused by open-pit coal mine fire area in Xinjiang,based on existing geological data and actual site surveys,combined with microscopic structural and physicochemical property tests,the article conducts a multi factor sensitivity slope stability calculation and analysis,studies the influence of the erosion temperature of the fire eroded coal rock on the macroscopic morphology of the strongly expansive soft rock,and the macro and micro variation laws of the compressive strength of the strongly expansive soft rock with the erosion temperature.The article quantitatively analyzes the stability of existing fire eroded coal rock slope and the stability of continuous rainfall infiltration at different times,and determines the variation law of the stability coefficient of the eroded coal rock slope with external conditions.关键词
