Embodiment Construction

[0033] The present invention provides a fire prevention and extinguishing method for coal gangue hills. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] The invention provides a method for preventing and extinguishing fires of coal gangue hills, which comprises the following steps:

[0035] Include steps to identify spontaneous combustion fire zones within coal gangue dumps;

[0036] Including the step of pre-cracking the coal gangue pile in the spontaneous combustion fire zone;

[0037] It includes the step of injecting and cooling the coal gangue after the above-mentioned pre-cracking and antireflection.

[0038] Furthermore, the above-mentioned steps of determining the spontaneous combustion f...

Abstract

The invention discloses a fire prevention method for a coal gangue mountain. The fire prevention method comprises the steps of: determining a spontaneous combustion fire area in the coal gangue mountain; performing presplitting permeability improvement for the coal gangue mountain in the spontaneous combustion fire area; and performing injection cooling for the coal gangue mountain after the presplitting permeability improvement. The fire prevention method can effectively determine the spontaneous combustion fire area, then performs the permeability improvement and the cooling for the spontaneous combustion fire area of the coal gangue mountain by using a presplitting permeability improvement system, and finally injects a composite inhibition foam material in the spontaneous combustion fire area of the coal gangue mountain by using an injection system, so that a high-temperature point is reduced below a spontaneous combustion fire point of coal gangue, oxygen is isolated, the purpose of preventing coal gangue fire is radically achieved, and the governance effect on the coal gangue mountain is improved.

Description

technical field [0001] The invention relates to the field of treatment of mine waste, in particular to a fire prevention and extinguishing method for coal gangue hills. Background technique [0002] Coal gangue is an inevitable product in the coal mining process, accounting for about 15% of raw coal output, and is the largest industrial solid waste in my country. Coal gangue contains pyrite, sulfur, coal powder and other substances, which are prone to spontaneous combustion when exposed to the surface for a long time, and can release a large amount of toxic and harmful gases, such as SO 2 , CO, H 2 S, etc., threaten the surrounding environment and the health and personal safety of surrounding residents and mine safety. In addition, heavy metals in coal gangue are released into surface water and groundwater due to the erosion, leaching, and acid effects of rainwater, causing heavy metal pollution and deteriorating the environment; Due to the large slope of the coal gangue p...
