Metal mine refuge chamber system

Abstract

The invention discloses a metal mine refuge chamber system. The metal mine fugue chamber system comprises an oxygen supply sub system including a compressed air system oxygen supply mode, a compressed oxygen supply mode and a self-rescuer oxygen supply mode, a dehumidifying and cooling sub system, an air purifying sub system, a protective closing sub system, a power supply sub system, an environment monitoring sub system and a communication sub system. Moreover, the metal mine refuge chamber system further comprises an emergency air exhaustion device and an accessorial sub system. The metal mine refuge chamber system solves the problems that the existing metal mine refuge chamber system has no formed technology and product at home, cannot cope with catastrophes of metal mine, and is short in rescuable time. According to the invention, survival time of more than 96 hours can be provided in the chamber under the condition that the power supply is cut off by the catastrophes, basic survival conditions can be ensured by ventilating and exhausting via the corresponding pipelines when the roadway has serious water inrush or inundation, and emergency refuge of at least 96 hours can be provided when hazardous gases, fumes and poison gases appear in flood and fire hazard, and thus the metal mine refuge chamber system is applicable to the metal mine or underground engineering in a firm rock structure.

Description

technical field [0001] The invention relates to a mine disaster avoidance chamber system, more specifically, to a metal mine disaster avoidance chamber system. Background technique [0002] The construction of emergency avoidance system has been widely implemented in my country's coal mine industry, but it started relatively late in the field of metal and nonmetal mines. In recent years, with the increasing social demand for mineral resources and the enhancement of awareness of natural environment protection, it has become a trend for metal mines to shift from open-pit mining to underground mining. However, due to the gradual increase of mining depth and many factors, disasters such as roof fall, water inrush, subsidence, and fire frequently occur, causing huge damage to life and property and economic losses to enterprises and the general public, and seriously restricting the development of the national economy and mining enterprises. sustainable development. However, ther...

AI Technical Summary

Problems solved by technology

[0004] 1. The internal structure of the chamber and the technical parameters, quantity, and placement of equipment and facilities lack reasonable calculation and design, and overall design optimization is required to maximize the utility of equipment and facilities

[0005] 2. The indoor structural design of the tunnel did not take into account the real catastrophic environment underground, and did not carry out targeted research and development and design on the safety environment and hidden danger characteristics of each mine, resulting in a serious waste of resources

[0006] 3. Due to geological factors in metal mines, it is difficult to conduct large-diameter and precise drilling. At present, most disaster shelters do not adopt drilling; because the mining method of metal mines is different from that of coal mines, most disaster shelters are not drilled. It's a blind alley with only one safe exit

Therefore, none of the above underground disaster avoidance chamber systems can effectively protect against underground flooding disasters

[0007] 4. Not paying attention to the rationalized line layout of the combination of the disaster avoidance route of the whole mine and the chamber, and the facilities such as reflective signs and guide ropes are missing or unclear

[0008] 5. The mining side focuses on building permanent disaster shelters, ignoring the complementary role of temporary disaster shelters in the overall disaster avoidance system and permanent disaster shelters. Temporary disaster shelters are indispensable for emergency escape systems missing important components

[0009] 6. It is impossible to realize the close integration of the disaster avoidance room with the overall monitoring and communication system of the mine

Unable to achieve accurate disaster warning, did not play the role of disaster shelter asylum
