Mine construction safety early warning escape system

Abstract

A safety early-warning escape system for mine construction comprises a plurality of early-warning escape devices arranged in a roadway and a control device arranged outside a mine, each early-warning escape device comprises an early-warning module and a survival module, the early-warning modules and the survival modules are arranged on the same fixing plate, and the early-warning escape devices are arranged on the same fixing plate. The early warning module and the survival module are connected through a wire, the back face of the fixing plate is tightly attached to the roadway wall of the mine to be fixed, the early warning module is connected with the control device through an optical cable, external personnel can know the water permeation condition in the mine through information returned by the early warning module on the control device, and optical fiber transmission signals are small in loss interference. The early warning escape system is simple in structure, long and accurate in signal transmission distance and suitable for being used under the mine, integrates the early warning function and the survival function, and greatly improves the survival rate of underground personnel when a water permeation accident occurs in the mine.

Description

technical field [0001] The invention relates to the technical field of mine safety production, in particular to a mine construction safety early warning and escape system as described above. Background technique [0002] Mine accidents refer to accidents that occur during the mining process, usually resulting in a high risk of casualties. At least thousands of people die in mining accidents every year in the world. Mine disasters can be caused by a variety of causes, including toxic gas leaks (hydrogen sulfide) or natural gas explosions (such as methane), coal dust explosions, seismic activity, floods, or mechanical failures and command errors. [0003] With the development of science and technology, roadway support technology and sensor technology are updated, mine disasters such as collapse, poisonous gas leakage and explosion are gradually reduced, but there are still no good protective measures for the protection of underground water seepage accidents, collapse, poisono...

AI Technical Summary

Problems solved by technology

[0003] With the development of science and technology, roadway support technology and sensor technology are updated, mine disasters such as collapse, poisonous gas leakage and explosion are gradually reduced, but there are still no good protective measures for the protection of underground water seepage accidents, collapse, poisonous gas Leakage and explosion can cause the death of those who encounter them in a short time, and the short-term survival rate is very low, while the short-term survival rate of flooding accidents is very high, but because of factors such as the difficulty of predicting and the high cost of rescue, there is still a high risk of flooding accidents. Mortality, encounters are often drowned or starved to death
