Description
Technical field
The utility model belongs to colliery and uses the lifesaving appliance field, relates in particular to a kind of refuge chamber protective door.
Background technology
On March 10th, 2010, national Coal Mine Safety Supervision Bureau organizes Eleventh Five-Year Plan national science and technology supporting plan one " research of movable type rescue capsule for mine key technology " project by checking and accepting.On July 19th, 2010, State Council has issued " State Council is about the notice of further reinforcement enterprise safety operation work " (No. [2010] 23, promulgated by the State Council), requirement in colliery, formulate in the non-coal mine field and implement the Technical facilities in production standard, installation and measuring monitoring system, Mine Personnel Positioning System, urgent danger prevention system, compressed-air self-help system, water supply sue and labour system and liaison " six large systems ".On August 24th, 2010, August 30, national security supervision general bureau, Supervisor Bureau of Coal of country has issued " colliery Work Safety Supervision Bureau of country of national security supervision general bureau improves the notice of coal mine downhole safety hedging " six large systems " about construction " (No. [2010] 146, total coal dress of safety supervision) and the implementation guideline of the work of the practical reinforcement of spirit Safety of Coal Mine Production " colliery Work Safety Supervision Bureau of country of national security supervision general bureau is about conscientiously the carrying out State Council<notice > " (the total coal of safety supervision is supervised [2010] No. 152) in succession, construction is improved to safety of coal mines hedging " six large systems ", particularly the underground emergency avoiding system has been made Compulsory Feature.On January 25th, 2011, national security supervision general bureau, national Supervisor Bureau of Coal have printed and distributed " emergent danger avoiding system under shaft of coal mine implementation management temporary provisions " (hereinafter to be referred as " temporary provisions ").Country is for a series of regulations at colliery and non-coal mine field mandatory carriage " six large systems " and require to provide good policy assurance and the market demand for development and popularization underground emergency avoiding system energetically.
At present, external mine escape capsule and refuge chamber manufacturing enterprise mainly concentrate on the minority mining industry developed countries such as the U.S., Australia, Canada, South Africa, its product mainly is divided into four classes: the first kind is the steel survival capsule, hold specification and do not wait from 8 people to 32 people, product size is according to down-hole actual conditions special setting; Equations of The Second Kind is the inflated soft survival capsule; The 3rd class is the transition station; The 4th class is the permanent refuge chamber in down-hole.External survival capsule product is according to its mine working condition and emergent rescue capability, consider it is more the effect of supporting one's family of product, mainly provide the necessary material of life to be equipped with, as oxygen, water, food etc., and, for the safeguard function of antiknock, high temperature resistance, its design standard is relatively low, what have does not even have air circulation and an air handling system, the time highest standard of supporting one's family is designed to 64 hours (as the U.S.), and the antiknock standard is 0.1MPa.From working condition and the emergent rescue capability of the existing mine of China, the antiknock standard of 0.1MPa does not have safety protection function in most of mine disasters, and the time of supporting one's family of 64 hours is too short.The more important thing is, once mine disaster occurs, must cause the damage of the original electric power of mine and ventilation equipment, can't provide continued support for survival capsule.This just need to be according to domestic mine working condition, and development is applicable to the emergency management and rescue danger-avoiding facility of China's national situation.
Mine escape capsule is the crash equipment after the accidents such as coal mine gas, coal-dust explosion, Gas Outburst, landslide, roof fall occur, and can be widely used in the mine of various geological conditionss.Provide act of rescue place for the down-hole distress personnel while being mainly used in mine disaster occurs.When mine disaster occurs, externally can resist blast impulse, high-temperature flue gas, roof fall and cave in, isolated toxic and harmful; Internally, for the hedging miner provides oxygen, food, water, remove toxic and harmful, for the miner wins longer survival time, simultaneously can be by the extraneous rescue of the guiding of the communication apparatus in cabin.
