Description
Technical Field
[0001] The utility model relates to the technical field of preventing personnel from falling, and more specifically to a device for preventing personnel from falling into a coal bunker in an underground coal mine. Background Art
[0002] Coal mine underground operations refer to various work activities carried out underground in coal mines. Coal mine underground operations include coal mining, tunneling, support, ventilation, drainage, transportation and other links. The first is coal mining operations, that is, taking coal out of the coal seam through equipment such as coal mining machines. Coal mining operations are usually divided into two links: mining working face and auxiliary mining working face. On the working face, workers need to perform operations such as drilling, blasting, tunneling, etc. to open up the coal mining area; while on the auxiliary mining working face, workers perform cleaning, support, coal transportation and other work. The second is tunneling operations, which mainly refers to the development of new shafts and tunnels. In this process, workers use tunneling machinery or carry out manual tunneling to expand the scale of the mine and the number of passages. Support operations refer to supporting and reinforcing coal mine shafts to prevent geological disasters and collapses. Support operations mainly include setting pillars, grouting, anchor bolts and other operations. Ventilation operations are to ensure the circulation and freshness of air in the mine to ensure the safety and health of workers. Ventilation operations are mainly composed of air shafts, ventilators and air ducts. Fresh air is introduced into the mine through air shafts or ventilators and harmful gases are removed. Drainage operations are to remove water from the mine to keep the mine dry and operating normally. Drainage operations mainly use pumps to pump water out of the mine and drain the water out of the mine through drainage equipment. Transportation operations are to transport the coal mined by the coal mining machine to the ground for processing and sales. Transportation operations are usually carried out by equipment such as conveyors and trucks in mines. In general, underground coal mine operations involve all aspects of coal production, including coal mining, tunneling, support, ventilation, drainage and transportation, and are indispensable work in the coal mine production process.
[0003] There are still accidents where people mistakenly enter underground coal bunkers. Currently, wooden boards and guardrails are often used for protection, but the effect is not ideal and there are certain safety hazards. Therefore, a new technical solution is needed to solve the problem. Utility Model Content
