Mining spraying materials for sealing coal bodies, coal mine spraying materials for fire and gas prevention

Description :

　　Mining spraying materials, coal mine spraying materials, enclosed coal body, fire and gas prevention

　　understandMining spraying materialsThe basic purpose of is to be responsible to the user unit as a way,Coal mine spraying materials are used to seal coal bodies for fire and gas preventionWhen enterprises choose materials based on their tunnel conditions, they must identify the differences among various materials. Spray coating material - is a two-component polymer slurry used to prevent coal spontaneous combustion, isolate air, and prevent gas leakage. It plays an irreplaceable role in coal wall sealing due to its high expansion rate, high bonding strength, and high safety when sprayed on the surface of coal seams, while expanding and condensing to achieve a sealing effect.

　　1、 Mining spraying materialsTechnical Specifications:

　　Product Characteristics: Component A, Component B

　　Use a mixing ratio (volume ratio) of 1:1

　　Reaction time (S) 5~40 (adjustable)

　　Compressive strength/MPa2~10

　　Adhesive strength/MPa 1-5

　　Expansion factor 5-20

　　Flame retardant properties

　　IICoal mine spraying materials are used to seal coal bodies for fire and gas preventionThis is its scope of application, and it has more applicable areas:

　　Spraying on the surface of coal pillars to prevent harmful gas leakage and spontaneous combustion of coal seams caused by air leakage between goaf and mining area; Protect the concrete spraying surface of the main alley and spray the surface of the brick and stone enclosed walls and coal wall cracks to prevent harmful gas leakage; Spraying on the surface of the excavation roadway can greatly increase the safety of construction by avoiding large-scale irregular leaks caused by gas during excavation in coal mines; It can also be used to construct fast sealed walls, etc.

　　3、 Mining spraying materialsFeatures:

　　1. High expansion rate: reduce material usage;

　　2. Strong adhesion: quickly and firmly adhere to the surface of coal;

　　3. Low viscosity: Penetrating into microcracks;

　　3. High toughness: sufficient to adapt to rock movement.

　　A company is not defined by its name, articles of association, and company regulations, but by its mission. The same goes for enterprise products,Mining spraying materialsThe task is to seal and expose the coal body, isolate the air, prevent coal spontaneous combustion and gas leakage,Coal mine spraying materials are used to seal coal bodies for fire and gas preventionOnly with clear tasks and objectives can the set plan goals be achieved. Our factory produces mining reinforcement materials, mining water blocking materials, mining filling materials, mining sealing materials, mining hole sealing materials, etc. Shandong Hongyi Technology Xiaozhang looks forward to your inquiry.
