Embodiment 1

[0036] Such as Figure 1~3 As shown, a fully mechanized mining working face magnetized surfactant gas coal dust collaborative prevention and control device, including a solution compounding device 1, a magnetized water generating device 2, a pressurizing device 3 and a spraying and injecting device 4; the solution compounding device The device 1 is connected to the magnetized water generating device 2 through a pipeline, and the pressurizing device 3 is respectively connected to the magnetized water generating device 2 and the spraying and injecting device 4;

[0037] Based on the above structure, the surfactant is prepared by the solution compounding device 1, and then the prepared surfactant composite solution is pumped into the magnetized water device, and the surfactant composite solution is magnetized in the magnetized water generating device 2, Then in the coal mining face and coal seam 44 by spraying and injecting device 4, the tensio-active agent that injects coal seam...

Embodiment 2

[0045] The invention provides a method for synergistic prevention and control of gas and coal dust with magnetized surfactant in fully mechanized mining face, which specifically includes the following steps:

[0046] Step 1: store different base liquids in multiple liquid storage tanks 11, control the flow of each base liquid by adjusting the rotameter 12, and prepare a surfactant compound solution with an appropriate concentration; use a booster pump 13 to Surfactant complex solution for delivery and mixing;

[0047] Step 2: Slowly and efficiently magnetize the prepared surfactant composite solution in the magnetized water device;

[0048] Step 3: Pressurize the magnetized surfactant composite solution and transport it to the coal seam 44 and the coal mining face to suppress and degrade the coal dust and gas.

[0049] The present invention mainly prepares a certain concentration of surfactant solution (one or more surfactant compound) through a surfactant preparation device,...

Abstract

The invention discloses a device and method for synergistically preventing and controlling comprehensive mechanized coal mining face magnetized surfactant gas and coal dust. The device comprises a solution compounding device, a magnetized water generating device, a pressurizing device and a spraying and injecting device, wherein the solution compounding device is connected with the magnetized water generating device through a pipeline, and the pressurizing device is respectively connected with the magnetized water generating device and the spraying and injecting device; a surfactant preparation device comprises liquid storage tanks, a rotor flow meter, a pressure pump and a main pipeline, the liquid storage tanks are connected with the rotor flow meter, the rotor flow meter is communicatedwith the main pipeline through the pressure pump, and the main pipeline is communicated with an external water supply system; and the plurality of liquid storage tanks are arranged along the liquid flowing direction of the main pipeline. According to the device and method, cooperative prevention and control of the gas and coal dust are achieved, the dust concentration can be effectively controlled while gas desorption is restrained and the gas concentration is reduced, and the working environment of a working face is improved; and the purpose that one device has multiple functions is achieved, cost is saved, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of shaft coal mine operations, in particular to a device and method for synergistic prevention and control of magnetized surfactant gas and coal dust in a fully mechanized mining face. Background technique [0002] Coal mines will produce a lot of coal dust in the process of excavation or mining; according to statistics, coal roads can produce 818.3mg / m per minute during the excavation process 3 Dust seriously pollutes the underground working environment. Studies have shown that long-term exposure to high dust concentrations in the working environment can lead to irreversible and fatal lung diseases, currently mainly manifested as pneumoconiosis (CWP), chronic obstructive pulmonary disease, tuberculosis, chronic bronchitis, emphysema, etc.; by According to the occupational disease data released by the International Occupational Health Association in 2019, confirmed cases of pneumoconiosis account for 90% of...
