Water injection hole blocking material / mine gas blocking material price low injection hole blocking material gas blocking material blocking material mining blocking material morning, the people of the earthquake-stricken areas in Yunnan Yiliang gathered in the rest of the open space. As of press time, the Yunnan Yiliang earthquake has caused to 74.4 million people were affected, 67 people were killed and 731 people were injured, and the direct economic losses of 3.5 billion yuan. Next, we explain how the blocking material construction, construction personnel strictly enforce the "first check" and "knock help ask top" system, work during construction, in strict accordance with measures to put an end to the illegal operations. 3, you want to work in front of access to coal to help construction downpipe latching switch hit stop, and execute the system first checks after work and knock the help asked top. 4, work, arrange to place of work in and around the roof custody inspection found unsafe to be in time, to ensure the safety of construction. 5, drill, non other officers standing on both sides of the drill rod, prevent broken brazing wounding. Drill during roof than crushing or serious slabbing rely on coal to help the side with the monomer of 2.8 meters with 1.8 meters roundwood Supporting good roof or coal to help with semicircular wooden back good top to help take the care to help column. 7, the longwall high control between 2.1 ~ 2.4m before the probe beam damage, since the fall of the column to be repaired in time to replace. 8, to ensure that the the face supports in force of not less than 24MPa. Is fully filled rock joint, improve the grouting quality, every row made holes grouting method used in the construction process. 10 grouting conscientiously observe the pressure gauge and face the situation, identify problems immediately shut down processing, non-pressure control grouting, slurry leakage appears timely sealing. 11, when the other eye position or to overhaul pump and piping must be relief post-processing, non-personnel standing before the relief valve pressure relief discharge slurry. Non with the pressure of work. 12, the maintenance staff in the addressing electromechanical accident or equipment take rejection fire non-live working blackout signs must be linked to a power outage. 13, grouting, Put on labor protective clothing to prevent accidents and injuries. 14, the construction materials used to classify neatly stacked, clearly marked. 15, each time to go hook cut coal downpipe within sundries must seriously clean. Coal drill pipe and other objects to the specified location stacked. 16, to participate in the construction personnel to do to look after each other, cooperate with each other, coordinated to prevent accidental injury. 17, strictly the implementation of the multifunction syringe pump operating manual, the construction process manual. Taian Fu through production the mine fan ore with damper Dust Blower deviated explosion-proof doors Shaft Explosion Door the balance damper mine filling materials, a series of ore bearing ore with the Tiandu material mining products, welcome to visit our factory, blessing through your choice!
