Embodiment 1

[0025] This embodiment is a hand-held mine water inrush source rapid identification device implemented according to the technical solution of the present invention.

[0026] figure 1 It is a structural schematic diagram of the mine water inrush water source rapid identification device of the present invention. refer to figure 1 As shown in , the mine water inrush source rapid identification device of this embodiment includes: a circuit board A placed inside the casing C1, the casing C1 is provided with a power input interface C11, a power on / off button C3, a mode changeover switch C2, Display screen A2, Micro-USB interface A7, ion electrode connection line interface C12, and function buttons C4~C10: respectively, four-way control keyboard combination C4, function button C5 for setting the water source type to be identified, and constructing water inrush sources according to water quality samples Discrimination process system function button C6, water inrush water source disc...

example 2

[0065] (3) In Example 2, there are few samples of karst fissure water in the Taiyuan Formation. According to the water samples of other mines in the same hydrogeological unit nearby, you can open the setting mode of the controller in this device and use the function button to set the water source type. Adjust the discrimination system, that is, use the control keyboard as the control input to set the parameter with the discrimination order number 3, select the Taiyuan Formation karst fissure water from the water source types to be identified, and select "sulfate ion" as the water source type from the water sample ion indicators For the characteristic ions, set the threshold value of sulfate ion used to distinguish the selected water source type as "350", set the discrimination relationship used in the discrimination as "greater than", and adjust the discrimination process system through the above operations.

[0066] (4) When a water inrush event occurs, take 30-100 ml of water...

Abstract

The invention discloses a device for rapidly distinguishing a water inrush source of a mine. The device comprises a shell panel which is provided with a power input interface, a switching on / off button, a mode conversion switch, a function button, a display screen, a micro-USB interface and an ion electrode connecting line interface; a circuit board arranged in a shell takes a singlechip as a core and is connected with the display screen, an A / D conversion module, a memory, the function button, the micro-USB interface and a power module. A method for building a water inrush source distinguishing process system comprises the steps of automatically building a characteristic ion-based distinguishing process system for the water inrush source of the mine by analyzing a known water source category sample in the memory; detecting the water sample by an ion electrode; calculating to obtain actual ion concentration by use of the singlechip according to a Nernst equation; and rapidly distinguishing according to the water inrush source distinguishing process system. According to the device, the characteristic ion detection and the water inrush source distinguishing are integrated, the sample is automatically analyzed, and the distinguishing system is built; the device is high in distinguishing speed, high in accuracy rate and convenient to carry.

Description

technical field [0001] The invention belongs to the technical field of water quality analysis and water source identification, and in particular relates to a hand-held mine water inrush source rapid identification device based on characteristic ions. Background technique [0002] Mine water inrush is a long-standing hydrogeological disaster in the development of coal resources, which can easily cause heavy economic losses and casualties. The problem of mine water hazard has always been one of the major technical issues in my country's coal production, and almost all mines are faced with varying degrees of water hazards. Once the water inrush occurs in the mine, the primary task is to quickly and accurately judge the source of the water inrush, so as to take corresponding prevention and control measures to reduce or avoid major accidents such as well flooding. Groundwater hydrochemical data are the most essential characteristics of groundwater. One of the most effective way...
