The Wet Shotcrete Technology and application Effect in Underground Coal Mine

Yang Qiu

Abstract


summarizes current situation The wet shotcrete in Underground coal mine, contrast the Advantages and Disadvantages of of two ways The TransportationWith stirring , analyzes , parameters To current wet shotcrete Sprayer then Development level of spray manipulator , points out the main indexes and methods of Control and Monitor of quality. contraction experiment a dry and wet shotcrete in underground Coal mine shows so : wet shotcrete Can decrease 80% of environmental Dust concentration and 70% of rebound ratio , increase , thickness of once- Spray-layer From $ mm to $ mm . The application effect in wet shotcrete is very do .
