Problems solved by technology

[0008] The technical problem to be solved by the present invention is how to overcome the existing technical difficulties and realize the change of the water level in the dump area in the process of the dump site from scratch, that is, before, during and after the mining of the open-pit mine, so that There are sufficient data to support the follow-up studies on the stability of the dump itself, the safe mining of coal mines, and the reclamation of surface land; for this reason, the present invention provides a mine dump with simple structure, low cost, and easy operation.

Embodiment 2

[0073] The method for using the multi-water type real-time monitoring device in the mine dump of the present invention comprises the following steps:

[0074] (A) find the center position of the dump site 1 according to the designed drawings;

[0075] (B) drill holes to form the vertical section 301 of the second measurement well 3, install the second water level sensor 9 therein, and adopt the second cable 10 to be fixed on the fixed pulley 8 to detect the water level change;

[0076] (C) After 2 to 3 months, the open-pit mine starts to mine the working face, and starts to strip the topsoil layer in the pit area to the dump site 1. At this time, the self-sealing casing 11 is laid to form the horizontal section 302, and the second cable 10 is plugged in from the first cable seam 12, and is connected to the soil pile yard 1 beyond the soil pile range;

[0077] (D) Continue to pile up the soil. After 1 to 3 months, the pile of soil 1 is gradually piled up to a height of 5-8m. A...

Abstract

The invention provides a multi-water-type real-time monitoring device for a mine soil dump site. The device comprises an above-ground part and an underground part. The above-ground part is located at a soil stacking site (1) above the original ground. The multi-water-type real-time monitoring device for the mine soil dump site comprises a first measuring well (2) and a second measuring well (3), wherein, the first measuring well (2) is made by connecting multiple self-sealing sleeve pipes (11) in a top-to-bottom mode. The uppermost self-sealing pipe (11) is provided with a suspended water monitoring device which comprises a data processing box (14), multiple pairs of electrode probes (15), a buckling groove (16) and a soil monitoring pipe (17). The multi-water-type real-time monitoring device for a mine soil dump site has the advantages of being simple in structure, low in cost and convenient to operate.

Description

technical field [0001] The invention relates to a mining machine, and is especially suitable for a real-time monitoring device for multiple water species in mine dumps and a use method. Background technique [0002] Open-pit coal mining directly strips the topsoil and the overlying rock of the coal seam to expose the coal seam before mining, and the stripped rock and soil are piled up in layers inside and outside the mining area to form a dump site. Large-scale dumps are artificial giant piles formed by the mixed accumulation of rock and soil in the mining area. During the accumulation of large-scale dumps, the change of water level in the dump area plays an important role in regional environmental assessment and early warning of coal mine safety production. [0003] The process of a dump from scratch is actually the process of mining the entire open-pit mining area, but there are few studies on it now. Some teams have deployed several logging wells in the area around the d...
