Abstract

The invention discloses a mining spraying material formula which is characterized in that: the spraying material comprises a solid material and a liquid material; the solid material comprises the following components: cement, fly ash, a water reducer, an accelerating agent, and fibers; the liquid material comprises at least one of acrylic acid emulsion (pure acrylic acid, styrene acrylate, modified building styrene acrylate, butylbenzene) or 801 glue; the mass ratio of the solid material to the liquid material is 100:3-10; the spraying material formula of the invention is suitable for rapid construction, has no dust or springback during construction, is green, environment-friendly, material-saving, and good in flexibility, is not liable to cracking, does not flake to hurt people even if cracking occurs, and is high in safety and reliability.

Description

technical field [0001] The invention relates to a mineral spraying material formulation and a using method. Background technique [0002] At present, the well-known thin spray for mining is mainly dry spray. Although the spray layer after spraying has a certain supporting effect, its effect is small, the bearing capacity is poor, and the spray layer is easily cracked under pressure, and even slurry appears. The skin peels off in a large area, which brings great hidden dangers to safety production. At the same time, the utilization rate of traditional shotcrete materials is low, the dust is large, and the rebound rate is high, so the construction environment is poor and there is a lot of waste. In addition, the construction speed is slow, and the requirements for auxiliary transportation are large. The shortcomings of these roadway spray protection technologies restrict the development of modern mines. Therefore, a shotcrete material and shotcrete technology with excellent p...
