The invention relates to the technical field of emergency rescue of mine flood accidents, in particular to a trackless inclined shaft floating pump type emergency drainage system for a mine and an installation method thereof.
Background
The number of mines in China is large, the mining extends to the deep part, and the water inflow of the mines tends to increase. In recent years, mine flood accidents mainly involving inclined shafts are in the period of easy occurrence, and as the mining depth increases, water permeation accidents tend to be aggravated, so that the mine flood accidents become the second major disaster next to gas explosion, and a series of environmental and ecological problems can be caused. After a mine flood accident occurs, the key stages of mine emergency work are rescue and relief, water control and mine protection. The emergency rescue of the inclined shaft flood accident generally adopts a drainage operation mode that a mining relay pump is combined with a traditional mining centrifugal water pump and then is matched with a seamless steel pipe, a nodular cast iron pipe or an SEP composite pipe, the drainage operation mode is carried by a lower pump truck and a plurality of lower pipe trucks which are composed of steel wheel pairs, the drainage operation mode is realized by sequentially lowering the lower pump truck and the lower pipe trucks along a track by means of existing mine hoisting equipment, and then the drainage operation mode enables the water pump to be arranged above a moving water level after transitional connection combination among the water pump, a hard pipeline and the hard pipeline is completed. By adopting the water following and draining mode, a hard pipeline needs to be continuously supplemented and installed along with the continuous decline of the water surface so as to enable the water pump to be close to the water moving surface, and the following technical problems exist:
(1) for the mines with early construction times, underground transportation conditions are not perfect, railless, nonstandard track specifications and incomplete track laying are more, and the track is likely to be damaged after a disaster happens, so that a pump truck and a plurality of pipe trucks which are composed of steel wheel pairs are difficult to move;
(2) the mining centrifugal water pump has poor stability and reliability in the emergency drainage process of the inclined shaft, and is widely replaced by a mining submersible pump in actual application at present;
(3) the long-distance serial connection mode of a plurality of hard pipelines generally has the defects of heavy weight, large volume, poor maneuverability of underground traction transportation and lack of a quick connecting device, and the traditional mode of flange end face combination and bolt fastening is time-consuming and labor-consuming in installation;
(4) the technological processes of matching connection, integral movement, power supply and distribution of the water pump and the like of the water pump, a pipeline, a valve, a transition connection device and the like are complex, a plurality of auxiliary devices are provided, and matched auxiliary components such as power interfaces, plug-in units and the like have poor interchangeability and universality due to the fact that a unified standard and standard system does not exist, and rescue resultant force is difficult to form quickly;
(5) the conventional hoisting equipment for the mine fixedly installed cannot meet the actual requirements of large-range regulation and control of rope speed, multi-working-mode switching, flexible arrangement according to requirements and the like, and the conventional mining speed regulating winch is high in lowest rope speed, insufficient in rope capacity, small in traction tension during high-speed rope outgoing and lack of a power supply technical means suitable for system construction and integral movement.
(6) The field power supply condition is limited, the function of the equipment is incomplete, and the power drive and the comprehensive protection of the electric equipment cannot be realized.
The existing 38 national mine emergency rescue teams in China are mostly equipped with mine water pumps and supporting parts and auxiliary equipment required for transportation, installation and use, have the function of emergency drainage and are difficult to truly coil and activate drainage equipment due to the lack of professional technical training and field emergency treatment experience. When a mine breaks out major and above water-permeable accidents, 6 mine professional drainage stations are mainly relied on, wherein three northern drainage stations of Zhengzhou, Kai 28390and Peak mainly face a vertical shaft to construct a heavy drainage system which is vertically hoisted by a high-flow and high-lift mining submersible pump and a steel pipe, rail inclined shaft drainage also mainly depends on the steel pipe, and three southern drainage stations of Jiangxi, Shaoyang and Sichuan mainly correspond to small and medium inclined shaft water-permeable accidents, and a rail inclined shaft emergency drainage single pump mode, a series mode, a parallel mode, a grading mode and a residual water removal mode are constructed by matching with various mining water pumps. Therefore, a mature equipment system and a process mode suitable for lightweight and rapid construction of a trackless inclined shaft are urgently needed.
