Description
Technical field:
The present invention relates to monitor and early warning system and method, be specifically related to a kind of mining three-component magnetic wave two-way ground monitoring and warning command system and method.
Technical background:
Coal is the main body energy of China, and within 2013, national raw coal output reaches 3,700,000,000 tons, increases by 76.2% than 2005; The Eleventh Five-Year Plan period the whole nation is accumulative produces coal 13,900,000,000 tons, for national economy and social development provides important support.Because China's coal-mine ore bed buries comparatively dark, be suitable for opencast reserves and only account for 4%, majority is pit mining.Complicated geological conditions result in the disaster such as toxic and harmful, dust, permeable, fire, top board and takes place frequently.Achieve situation of production in recent years to take a turn for the better continually and steadily, but safety in production field still exists some problems, also there is a big difference, and accident plays number and death toll is still in a high position, and situation of production is still severe.According to incompletely statistics, 2008 to 2012, colliery production development accident 74, stranded number reached people more than 800, relates to the various disaster accidents such as coal mine gas, fire, floods, top board.
The reason that China's coal-mine Safety production questions takes place frequently is a lot, wherein safety in production technology equipment backwardness relatively, still enough technical supports and guarantee can not be provided to be one of its reason for safety in production, therefore, in " great production accident early warning and rescue " in " National Program for Medium-to Long-term Scientific and Technological Development (2006-2020) " " public safety " field preferential theme, " primary study exploitation mine gas is clearly proposed, gushing water, dynamic property disaster alarm and Control Technology, exploitation burning, blast, the substantial industrial accident prevention and control such as Toxicant Leak and rescue technique and relevant device ".In " safety in production " 12 " planning ", also " scientific and technical research of strengthening safety in production ", " applying advanced and applicable technology and equipment, raising safety assurance ability " are classified as the important content of six large tasks.Send out in (2013) No. 99 General Office of the State Council " suggestion about strengthening Safety of Coal Mine Production work further " the Office of the State Council in 2013 simultaneously and also explicitly point out the construction will strengthening colliery emergency and rescue equipment.
Because radio communication system conventional at present cannot effective earth penetrating, what therefore generally adopt in existing solution is wire communication, and once cave in or explode just can destroy wire cable cause as personnel positioning network, communication network paralysis, after disaster accident occurs, down-hole distress personnel cannot be set up with ground rescue personnel and contact, ground staff cannot grasp the rear personnel's distribution situation of accident generation simultaneously, causes blindness and the rescue inefficiency of rescue.
Middle nineteen nineties in last century, the external U.S. and Australia have succeeded in developing " PED downhole wireless first aid paging system ", but this system can only send unidirectional information from aboveground to personnel in the pit, and underground work personnel cannot to aboveground transmission of information; LockheedMartin company of the U.S. development MagneLink thoroughly communication device, StrataWorldWide company of the U.S. RockPhone thoroughly communication device, Canadian VitalAlert company development Canary communication device thoroughly, domestic Tiandi (Chuangzhou) Automation Co., Ltd., Shanxi Hao Yulongsheng Electronic Science and Technology Co., Ltd., branch company of Jinzhong City of Shanxi Dibao Technology Co., Ltd. by autonomous or with external several companies R & D Cooperation communication device thoroughly, but communication distance is shorter.Within 2013, the average mining depth of China's coal-mine is more than 600m, has the most reached 1500m, and with annual 10-20m speed increase, prior art can not adapt to most of colliery actual conditions; Do not have that personnel's distribution situation after occurring disaster is grasped simultaneously, environmental parameter monitoring, analyze and early warning ability and and colliery existing network incompatible, easily form the shortcomings such as information island, cause also failing to be widely applied in colliery at present.
