Abstract
The invention discloses a water-seepage-free, stuffy, humid and permanently-sprayed concrete supporting roadway white spraying coating and a construction method thereof. The coating comprises a coating A and a coating B. The construction method of the coating comprises the steps that the wall of a roadway is coated with the coating A, and after drying, the wall of the roadway is coated with a mixture of the coating A and the coating B. The problem of potential safety hazard of the permanent concrete-spraying support water-seepage-free stuffy and humid roadway of an underground mine is solved;a special paint and the process method are prepared through targeted research; a safe, economical and efficient method is adopted to spray a white coating on the roadway; the problems of quickly preventing roof fall and rib spalling potential safety hazards and monitoring ground pressure change of an underground mine are solved by a simple and visual method; the overall illumination brightness canbe increased by 50% or above on the original basis, obvious black burr cracks can be shown on the coating when the potential safety hazard of roof fall and rib spalling occurs, an operator can quickly and visually master the roadway surrounding rock stability condition, prying is conducted in advance, pumice is treated, and safety accidents are prevented.
