Mine trackless inclined shaft floating pump type emergency drainage system and mounting method

Abstract

The invention relates to the technical field of mine flood accident emergency rescue, in particular to a mine trackless inclined shaft floating pump type emergency drainage system and a mounting method. A floating pump is suspended in water through a support and a floating boat, is pushed by a hard metal pipeline, a main pump and a matched pipe valve which are sequentially connected behind a water outlet of a floating pump along the gravity component of a slope;, a condition of rolling along the slope is created by a pipe supporting rubber wheel pair, a pump supporting truck and an emergency light rail, traction tension and rope outlet speed are controlled by a mining double-speed winch, a movable pulley block and a steel wire rope, so that the floating pump synchronously descends along with the water level at a low speed, a soft pipeline and a slow closing valve are connected behind a water outlet of the main pump in a matched mode, and a water source is safely conveyed at a long distance. Operation and monitoring of the floating pump and the main pump are guaranteed through power supply and distribution equipment, and voice communication devices are arranged at key points in a serialized mode to assist efficient linkage operation. According to the mine trackless inclined shaft floating pump type emergency drainage system, an integrated matching process technology solution and an optimally matched equipment system for lightweight and rapid construction of the trackless inclined shaft emergency drainage system are formed.

Description

technical field [0001] The invention relates to the technical field of emergency rescue for mine flood accidents, in particular to a mine trackless inclined shaft floating pump emergency drainage system and an installation method, which can be used in coal mines and non-coal mines that are mined by underground workers and have no or damaged transport tracks. After a flood accident, rescuers go deep underground to quickly build a floating-pump emergency drainage mode, so that the large flow can be drained to lower the water level, so as to buy time to search and rescue miners in distress and resume production as soon as possible. Background technique [0002] There are a large number of mines in our country, and the mining extends to the deep, and the water inflow from the mines shows an increasing trend. In recent years, mine flood accidents mainly involving inclined shafts are in a prone period. With the increase of mining depth, water seepage accidents have shown a tendenc...

AI Technical Summary

Problems solved by technology

[0003] (1) For some mines with earlier construction years, the underground transportation conditions are not perfect, there are many cases of trackless, non-standard track specifications, and incomplete track laying, and the track is very likely to be damaged after the disaster occurs, so that the steel wheel It is difficult to move the lower pump truck and several lower pipe trucks;

[0004] (2) Mine-used centrifugal water pumps have poor stability and reliability in the emergency drainage process of inclined shafts. At present, mine-used submersible pumps are widely used in practical applications to replace them;

[0005] (3) The long-distance series connection of multi-section hard pipelines generally has large weight and volume, poor maneuverability for underground traction and transportation, and lack of quick connection devices, and the traditional method of flange end face bonding and bolt fastening is time-consuming and laborious for installation;

[0006] (4) The matching connection of water pumps, pipelines, valves, transitional connection devices, etc., the overall movement, and the power supply and distribution of water pumps are complex, with many auxiliary equipment, and there is no unified standard for supporting accessories such as power interfaces and plug-ins. Standardized system, poor interchangeability and versatility, it is difficult to quickly form a joint rescue force;

[0007] (5) The existing hoisting equipment in fixed mines does not meet the actual needs of large-scale regulation of rope speed, multi-working mode switching, and flexible deployment on demand, while the minimum rope speed of conventional mining speed-regulating winches is high and the rope capacity is insufficient Moreover, the traction force is relatively small when the rope is pulled out at high speed, and there is a lack of power supply technology suitable for system construction and overall movement

[0008] (6) On-site power supply conditions are limited, and the equipment is incomplete, so it is impossible to realize the power drive and comprehensive protection of electrical equipment

[0009] There are currently 38 national-level mine emergency rescue teams in my country, most of which are equipped with mine water pumps and their supporting components and auxiliary equipment required for transportation, installation and use, and have the functional positioning of emergency drainage. experience, it is difficult to really revitalize the drainage equipment
