Embodiment 1

[0026] Such as figure 1 , 2 As shown, a combined drainage and sewage system suitable for mine "water inrush" disasters is composed of a plurality of drainage units 1 connected in series or in parallel; each set of drainage units 1 includes a complete set that can work independently or The combined working submersible sewage pumps 2 each have an independent power supply system and a drainage pipeline 3 with a full lift.

[0027] Among them, in the normal operation of the submersible sewage pump 2, it is necessary to avoid parallel operation of different types of pumps to avoid low-efficiency operating points, and to avoid using gate valves to control flow as much as possible to avoid increasing throttling losses; the submersible sewage pump 2 should be Bottomless valve operation is adopted, that is, the bottom valve at the suction end of the water pump is cancelled, the air in the submersible sewage pump 2 is pumped out by a jet vacuum pump, and the submersible sewage pump 2 i...

Embodiment 2

[0035] Such as image 3 As shown, when the water gushing volume of the water inrush roadway at the disaster site is large, in order to further improve the drainage volume and drainage efficiency, multiple drainage systems in Embodiment 1 can be connected in parallel to perform joint drainage operations. The specific implementation steps are as follows:

[0036] According to the flooding condition of the water inrush roadway, estimate the drainage flow rate and lift required on site, design and calculate the parallel arrangement scheme of the drainage pipeline 3 and the number of parallel drainage units 1 required;

[0037] According to the design requirements, the drainage pipelines 3 are arranged in parallel in the wellbore 4, and at the same time, the submersible sewage pumps 2 are transported to the wellbore 4 for installation and fixing, and the drainage pipelines 3 of each branch are connected in series with the submersible sewage pumps 2 respectively. Connect to the mai...

Abstract

The invention discloses a mine combined type water draining and contamination draining system and method. The system and method are particularly suitable for rapid emergency rescue of a mine goaf water inrush accident. The system is composed of a plurality of water draining units (1) connected in series or in parallel; each water draining unit (1) is a complete set of submersible electric pump (1) which can work in an independent or combined manner, is provided with an independent power supply system and a water draining pipeline (3) with a sufficient lift, and is convenient and rapid to mount; in case of a mine goaf water inrush accident, the water draining units (1) are connected in series or in parallel to form the water draining and contamination draining system, so that the purpose of rapid water draining and contamination draining for rescue is realized. The mine combined type water draining and contamination draining system effectively solves the problem that rapid water draining and contamination draining for rescue are carried out in case of a mine water inrush accident and can respond to various rescue environments more rapidly and flexibly to strive for more time for emergency rescue particularly under the circumstance that a goaf water inrush disaster, which contains violent water potential and high sediment content and has a high destructive effect, breaks out to flood the mine.

Description

technical field [0001] The invention relates to the field of emergency drainage for mine water disasters, in particular to a combined drainage and sewage system and method, which is especially suitable for rapid emergency rescue of mine "water inrush" disasters. Background technique [0002] Coal is the main energy source in our country, and the coal industry is the basic industry in our country. However, the special geological and geographical environment determines that the hydrogeological conditions of coal mines in my country are very complicated compared with other countries in the world. The mining of coal resources is seriously threatened by water disasters, and water inrush accidents occur frequently. Coal mine water disaster has become one of the major key issues affecting the safety of coal mine production in my country. [0003] The core technology of coal mine water disaster rescue is emergency drainage and sewage technology, that is, other rescue work is carrie...
