Abstract

The invention provides an underground coal mine personnel injury early-warning system. In coal mine production process, various types of injuries caused by machineries, particularly, mining and tunnelling working surface machinery, conveying machinery and the like, are also important factors causing the injuries and deaths of underground personnel. The early-warning system mainly comprises an underground mobile target, underground equipment, a communication network, a storage server, a monitoring server and a monitoring terminal; the monitoring server takes charge of monitoring the positions of mine personnel and equipment, giving an alarm signal when the monitored positions of the personnel and the equipment satisfy preset conditions, and providing a judgment method for the relation between specific personnel positions and a warning working area. The underground coal mine personnel injury early-warning system is an early-warning system which can monitor the safety of the working areas of the machineries automatically in real time, so that such injury accidents are prevented, and injuries and deaths of the personnel during a coal production process are reduced.

Description

technical field [0001] The invention relates to an early warning system for personnel injury in a coal mine, and the system relates to the fields of radio communication, underground safety monitoring and positioning technology and the like. Background technique [0002] The coal mine underground personnel positioning system is one of the "six major systems" for coal mine safety and avoidance. It plays an important role in the coal mine quota management and emergency rescue work, and effectively guarantees the safety of coal mine production. The coal industry is a high-risk industry. In addition to gas, flood, fire, roof, coal dust and other accidents, various mechanical injuries during coal mine production are also important factors that cause underground casualties, especially mining face machinery and conveying machinery. In addition to the necessary coal mine safety regulations and other systems and human management measures, the current coal mine safety monitoring system...
