Coating and method for easy identification of potential safety hazards in a small amount of water seepage, hot and humid roadway

Abstract

The invention discloses a coating and a method for easily identifying safety hazards of roof caving in a small amount of water seepage, sultry and humid roadway. The coating includes a primer, an intermediate coating and a top coating; the method drills water holes in water seepage cracks and installs aqueducts In order to guide the underground water seepage to the drainage ditch of the roadway; in addition, by spraying the alkali-resistant layer, the quick-drying waterproof layer and the white paint layer on the seepage roadway respectively, the white coating will prevent the safety hazard of the roof from falling. Obvious black burrs and fissures appear on the roadway, and the operators can quickly and intuitively grasp the stability of the surrounding rock of the roadway, and pry the pumice in advance to prevent the occurrence of safety accidents; The problem of ground pressure changes effectively improves the beautification of the underground working environment, and greatly improves the brightness of the roadway lighting; in addition, this method makes the safety hazards of the roof caving in the roadway obvious, and effectively improves the efficiency of roadway inspections.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a coating and a method for easily identifying potential safety hazards of roof caving in a roadway with a small amount of water seepage and sweltering heat and humidity. Background technique [0002] Underground mining is a high-risk industry. In the process of underground ore mining, the roadway surrounding rock is affected by factors such as geological structure, ground pressure activity, blasting vibration, corrosion and weathering, and roof fall accidents are prone to occur. According to relevant data, among all safety production accidents in underground mines across the country, roof caving accidents are the most frequent safety accidents, accounting for about 40% of all underground safety production accidents. The frequent accidents of roof caving not only cause economic and property losses of enterprises, but also bring misfortune to many workers' families. T...

Problems solved by technology

However, when there is a safety hazard in the side of the roadway roof, even if the concrete sprayed concrete layer cracks and there are signs of a roof collapse accident, it is still difficult for the operators to quickly and effectively identify it (the underground mine roadway environment is bad, The working conditions are poor, the lighting in the roadway is generally dim, and when cracks appear on the sprayed concrete layer, it is easy to mix with the texture of the surrounding sprayed concrete layer, which is difficult to distinguish in time and effectively, especially in areas with water seepage, the rock itself There are water seepage cracks, and the sprayed concrete layer covers the water seepage cracks, which makes it more difficult to grasp and observe the stability of the roadway surrounding rock)
