Description

Danger avoiding device for coal exploitation Technical Field The utility model relates to the technical field of coal exploitation, in particular to a risk avoiding device for coal exploitation. Background Coal mining is a process of mining coal from stratum and transporting the coal to the ground through underground or open air operation, in the mining process, disasters such as gas explosion, water permeation, coal dust explosion and the like occur, a danger prevention house is formed as an important facility for guaranteeing life safety of miners, and the coal mining safety device is generally composed of a high-strength shell, an oxygen supply system, communication equipment, food and drinking water storage, an environment monitoring device and the like. In the danger avoiding process, because the hand supporting device is lack in the danger avoiding house, when the outside shakes, danger avoiding personnel are difficult to keep body balance, risk of falling exists, threat to personal safety is possibly caused, and further optimization requirements exist on the safety aspect of the danger avoiding house, so that the application provides the danger avoiding device for coal exploitation to meet the requirements. Disclosure of Invention The utility model aims to solve the technical problem that when the outside shakes, the danger avoiding device for coal exploitation is difficult to keep the body balance, the risk of falling exists, and the danger of threatening the personal safety is possibly caused. In order to solve the technical problems, the utility model provides the following technical scheme: The utility model provides a keep away dangerous device for coal exploitation, includes keeps away dangerous room and rotates the roll-over door of connecting in keeping away dangerous room opening part, still includes: The hand assembly comprises an L-shaped handrail arranged in the danger avoiding room, and the L-shaped handrail is used for holding danger avoiding personnel during danger avoiding. Preferably, the side face of the danger avoiding house is provided with air holes, and the inner walls of the air holes are fixed with partition rods. Preferably, the protection plate is rotatably connected to the outside of the danger avoiding room and positioned at the air holes.
