Mine equipment operation safety risk points and prevention and control

① Mine disk saw operation requirements risk points and prevention and control. Check the condition of the equipment before running the circular saw, find out the security risks of the equipment in time, and handle them in time to ensure the safety of the equipment before operating. Mine circular saw controls the depth of each cut to prevent the phenomenon of card sawing from causing safety accidents. The speed of the circular saw in mine should be controlled to prevent the phenomenon of stuck sawing due to the excessive speed of the circular saw. Some circular saws are operated by people standing on them, and card saws pose a serious threat to human life safety when they occur. Often check the firmness of the teeth of the disc saw, and the loose ones are firmly welded. Saw blade teeth damaged seriously, should be replaced in time. During the operation of the circular saw in the mine, it is strictly forbidden to stay in the working area for a long time to prevent the injury of the circular saw to the people around.

② Mine disk saw blade installation risk points and prevention and control. The installation of the mine disc saw should be carried out by professional maintenance personnel. When installing a circular saw, ensure that the nut is tight.

③ Risk points and prevention and control of raw material and plate loading and unloading. After the disc saw is finished cutting the waste material or the plate, the waste material and the plate should pay attention to safety during the unloading process. If the unloading method is improper or careless, it is easy to cause accidents and even lead to casualties.

④ Mine disk saw equipment failure treatment. Mine circular saw failure, should be by professional maintenance personnel to check the circular saw, deal with equipment failure, to ensure the safety of equipment.

⑤ Safety precautions when the mine disk saw is shifted. Mine circular saws need to move frequently as the mining height changes. The disk saw should be responsible for the shift, if necessary, the development of safety measures plan, strictly according to the safety measures plan for the shift work, to ensure the safety of equipment and personnel during the shift of the disk saw.

(4) Mine diamond beaded rope operation safety risk and prevention and control

Mine diamond beaded rope saw injury accidents have been heard of several, the most serious accident has occurred in Italy Carrara white mine. It is said that the broken diamond beaded rope saw drove the cracked stone to hit the staff at the working face, and the mine stopped production for a long time and suffered huge losses. Domestic mines have also occurred diamond bead rope broken throw injury accident. With the popularity of diamond beaded rope saw, stone production enterprises should pay attention to the control of safety risk points of diamond beaded rope saw operation and reduce mine production accidents.

Mine diamond beaded rope saw operation safety risk control should pay attention to the following aspects:

① Diamond beaded rope installation must be firm. Diamond beaded rope running process suddenly thrown out to produce a huge force, if hit people will be killed immediately. Therefore, the installation of diamond string must be firm.

② Diamond beaded rope to control the number of joints. After the diamond beaded rope is broken, it will be connected with special joints to continue to use, but with the increase of the number of joints, the safety risk of diamond beaded rope saw is also increasing, which also poses a great danger to the operator of diamond beaded rope saw. Therefore, the number of diamond beaded rope joints must be controlled in a range that can ensure the strength limit of diamond beaded rope, and the number of diamond beaded rope joints cannot be increased without restriction in order to save mining costs.

③ The diamond beaded rope joint should be firm. The diamond beaded rope joint must be firm to ensure that the diamond beaded rope will not detach from the joint during operation. Apply appropriate pressure to the joint when connecting the rope. The pressure is small, the connection of the joint is insufficient, and it is easy to get away from the joint; The pressure is large, the pressure will break the joint, the strength of the joint is greatly reduced, and the diamond beaded rope is easy to pull away from the joint.

④ Diamond beaded rope is forbidden to be installed in a distorted state, when the diamond beaded rope is in a distorted state in production, the diamond beaded rope should be restored to a straight state with the force in the opposite direction of the distorted state. If the diamond beaded rope is twisted for a long time, the diamond beaded rope is easy to break during operation.

③ Diamond beaded rope running speed control. The reasonable running speed of the diamond beaded rope can not only ensure the safety of the operation of the equipment, but also reduce the broken rope caused by the diamond beaded rope running too fast. Diamond beaded rope operators cannot increase the running speed of diamond beaded rope in order to desperately pursue high output.
