Abstract

DRAIN (GROUND MASSIF, mainly in the extraction of minerals, including drainage fines, connected to the g-shm sump receiving chamber and diverging from the drift wells, and so with the aim of reducing costs and the duration of drainage on an inclined aqueduct, it is provided with a broadened drainage parallel to the drift up the slope, connecting the ends of the inclined-rising wells, and additional wells located in the upper hemisphere of the broadened drains at least one abutment at each deviated boreholes, each of the latter is mounted inside the filter tube from readily breakable material receiving chamber located at the end broadened drains; drift and located across a slope.

Description

The invention relates to the dewatering of underground workings, in particular, to the drainage of soil massifs with increasing drainage, advantageously during the extraction of minerals useful for: dangers. The drainage of the soil mass is well-known, including boilers formed by explosion and zones of fractured joints and channels filled with crushed stone 1J. The disadvantage of this drainage lies in the reduction of the Lltration properties of fine-grained rocks during explosive blasting. Moreover, the formation of boilers is technically difficult at a rapid distance, which reduces the efficiency of drainage of the soil. Closest to the proposed drainage of the soil mass during mining operations, including the drainage drainage drift, the receiving chamber with the sump connected to it and the waste well, from the drift, inclined-rising wells of C2. The disadvantage of this drainage is the large amount of preparatory workings and the complexity of their passage in undrained soil with the formation of a filter curtain, which leads to an increase in the cost of drainage and the duration of its implementation. The purpose of the invention is to reduce the cost and duration of drainage. The goal is achieved by the fact that the drainage of an array of soil, minerals are mainly useful for mining, including the drainage roadway connected to it, a receiving chamber with an HHPF and an inclined-recovered well bore from the liner. It is equipped with a parallel drift along the slope of the broadened tree connecting the ends of the inclined stationing wells and located in the upper hemisphere of the broadened drain of additional wells connected to the drains along the One at each place at -11 n: an on the well-rising wells, and each of them has a filter tube of easily destructible material installed inside, the camera is placed at the end of the wider / tpeTibi, and the pop rock bias,, 1 is depicted located e, than 1TO13 dre} 1azh on the site of drying PIA, in Fig, 2 - section A-A in figure 1; in fig. 3 shows the node I in FIG. 1. Drainage of the soil mass, preliminarily with the addition of useful minerals, has a drainage raft 1 located across the slope, which is combined with a hauling ave ;; following the development of array 2 of minerals, deviating from the drift 1, inclined-rising wells 3, which go up the slope with equal intervals between them, uniting the ends of the well 3 and 3, the broadened drain 4 located parallel to the drift 15 located at one end of the drain 4 a water receiving chamber 5 with a sump 6 connecting the chamber 5 with a drainage drift 1 of mine 7 and 8, consumed from an emergency drain 4 within its upper hemisphere additional wells 9 connected to the drain 4 at least one in each place adjoining inclined wells 3. Additional wells 9 have filter tubes 10 placed inside them with a filter screen (not -... cauldrons) and plug 1 1 at the outer end. Oblique recovery wells 3 also have filter tubes 12 made of easily destructible material that can be disintegrated along with minerals in their mechanized production, for example of polyethylene. In wells 3 there are removable packers 13 installed on rods 14. Width of drain 4 has a filter frame 15 with a wider gravel sprinkling 16. Drainage works as follows. After the gravel bedding 16 from the inclined-rising wells 3 are removed by means of rods 14 temporarily installed packers 13, which during the execution period of the drain 4 prevent the gravel from clogging up the inside of the filter pipes 12. When the array 2 is located, the minerals on the inclined aquifer 17 will receive the greatest amount of water from the overlying slope of the array 18. In this case, the main stream of water is intercepted by the broadened drain 4, and the water coming from the array 18, located on the bottom of the drain 4, is intercepted by an additional GOVERNMENTAL wells 9, koto3

If necessary, rye can be located not one at each place of adjoining wells 3, but several as a fan.

The groundwater that entered the drain 4 flows through the wells 9 and through the gravel dusting 16 by gravity into the receiving chamber 5 with the sump 6, from which the water supply 7 and 8 enters the drift 1 and further along it into the drainage system (not shown).

A part of the water from the drain 4 penetrates through the gravel bed 16 into the inclined-rising wells 3 and through them falls into the drainage drift 1, which is combined with the haulage drift during the extraction of minerals.

Water found n; a with in the array of 2 minerals and coming in

it from the overlying soil layers 18, is discharged through wells 3

also on drift 1.

As a result of the operation of wells 3 and 9 and the drainage 4, the groundwater is completely diverted from array 2 of minerals, while its level is established along line 19 to

t / fg.

This embodiment of the drainage eliminates the penetration of part of the drainage drifts, the functions of which are performed by the drainage and the well, which eliminates the need to conduct underground works in difficult hydrological conditions and thereby speeds up the work and reduces their cost.
