Abstract

The invention relates to a method for preventing after-combustion of gangue piles, and concretely relates to an after-combustion preventing gangue pile platform with checkerboard-shaped ditches, and agrouting method thereof. The method for preventing after-combustion is characterized in that the easy deforming, fracturing and spontaneous combustion parts of the gangue pile platform and its surrounding gentle slope are trenched in a checkerboard manner after the fire of the spontaneous combustion gangue piles is extinguished, and are grouted. The method has the advantages of easiness in operation, significant effect, long lasting time, solving of the spontaneous combustion prevention problem of the gangue pile platform, improvement of the integral stability of a gangue dump, and further solving of the selection problem of a grouting material and the monitoring of the temperature and the processing of a backfill layer after the grouting.

Description

technical field [0001] The invention relates to a method for preventing recombustion of gangue piles, and more specifically, to a checkerboard-shaped ditching prevention recombustion gangue pile platform and a grouting method thereof. Background technique [0002] In the process of coal mining, a waste with low utilization rate—coal gangue will be produced. The output of coal gangue is large in China. If the discharge is unreasonable, the spontaneous combustion of coal gangue in the later stage will cause great pollution. At present, there are many technologies for fire extinguishing and anti-resurgence of gangue dumps. Among them, grouting method is used to prevent recombustion, and some of them are surface spraying method and shallow grouting method. Such treatment methods are not easy to penetrate into gangue dumps, so they are not applicable. As for the overall anti-resurgence of gangue dump, the effect is not strong. Most of them use the drilling grouting method, and ...
