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, making it difficult to distinguish in time)

Abstract

The invention discloses a non-water seepage sultry hot and humid permanent spraying concrete support roadway spray white coating and a construction method. The coating includes coating A and coating B. The construction method of the coating is to apply the coating A to the roadway wall and then dry it. Apply a mixture of Paint A and Paint B to the roadway walls. According to the potential safety hazards in the permanent sprayed concrete support of underground mines without water seepage, hot and humid roadways, the present invention formulates special coatings and process methods through targeted research, and adopts a safe, economical and efficient method to spray white coatings on roadways, which is simple and intuitive. The method solves the problem of quickly preventing safety hazards of roof caving and monitoring changes in ground pressure in underground mines. The overall lighting brightness can be increased by more than 50% on the original basis. With black burrs and cracks, operators can quickly and intuitively grasp the stability of the surrounding rock of the roadway, and pry the pumice in advance to prevent safety accidents.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a non-seepage, sultry, humid permanent spraying concrete support roadway spraying white coating and a construction method. 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. There are many types of underground mine roadway...
