The contents of safety technical measures are as follows: 1. Only when all the coal in the bunker is empty can electric fire welding be used. 2. Before welding, notify the electromechanical department, ventilation department, safety supervision department and operation department to make preparations before welding. 3. Before welding, clean up all combustible materials at the front and rear ends of the construction site 10 meters, and spray water on all sides of the surrounding roadway. 4. Detect the gas concentration at any time before and during welding. When the gas concentration reaches or approaches 0.5%, it is forbidden to use electric welding, and the personnel shall be evacuated to safety quickly. 5, every time welding construction, construction director must take this measure to the scene, in strict accordance with the measures of construction. This measure should be applied to workers every time. 6, when using fire welding into the well, the fireman is responsible for carrying the igniter, as cutting gas, other workers are not allowed to carry any igniter, and all the igniters used when lifting the well are brought into the well. 7. Electric welding shall not be used above oxygen and acetylene cylinders. 8. In case of fire during construction, the power supply of electric welding machine, acetylene cylinder and oxygen cylinder valve shall be immediately cut off, and effective measures shall be taken to put out the fire. After the fire is extinguished and the hidden danger is eliminated, the construction can continue. 9, welders must hold relevant certificates, wear your own labor insurance supplies. 10, when using electric welding, strictly abide by the "coal mine safety regulations" and the relevant rules and regulations of the mine, and "three violations" are strictly prohibited. 1 1. The welding machine must be used alone, and the switch is not allowed to be used with other equipment. The welding machine must be connected completely, and the grounding wire is in good condition, and no leakage is allowed. 12, during construction, it is forbidden to use the geomantic pipes in the track and roadway as the ground wire, and the power supply of the electric welding machine should be attended by special personnel, and cut off the power supply at any time when it stops. 13. The construction site is equipped with two fire extinguishers and buckets, and water is guaranteed in the buckets. After welding, the residual fire should be extinguished at any time, and a special person should be appointed to stay for one hour to prevent the residual fire from rekindling. If any abnormality is found, it should be dealt with immediately. 14. After welding, sprinkle water on the job site to cool down, and the electric welding machine should cut off the power supply. 15, from beginning to end, the safety supervisor is responsible for supervising the implementation of the "coal mine safety regulations" and these measures. Those who violate the rules should stop work immediately, and the construction monitor should cooperate seriously and be highly responsible to ensure safe construction.
