Description

(54) METHOD OF MINE DRAINAGE

one

The invention relates to the mining industry and can be used for mine drainage.

The known method of mine drainage using drainage wells with subsequent pumping of water to the surface 1.

There is also known a method of mine drainage, including the drilling of rising wells from the production of solid aquifers 2.

However, both of these methods are not effective enough.

The purpose of the invention is to increase the efficiency of drainage.

The goal is achieved by those. that the revolving wells are drilled in the group by the group and simultaneously with the drilling of the group of the revolving wells in the mulder from the development of a group of downhole wells into solid water-absorbing rocks, after which the torpedoing of solid water-bearing and water-absorbing rocks is formed and continuous fracturing zones are formed and the revolving wells are formed with the formation of a single closed drainage system. :

The drawing shows a drainage system.

The method is as follows.

A group of ascending wells 2 is drilled out of production 1 in the mulde in hard rocks of the aquifer and in the hard rocks of the water-absorbing horizon, after the completion of the drilling, solid water-bearing and water-absorbing rocks are torpedoed with the formation of continuous fracture zones 4 and 5. Rising wells are connected to descending wells by connecting sleeves, a collector, a settler, and a filter. Water directly from wells 2 enters wells 3, mine mining.

Invention Formula The mine drainage method, which includes drilling of rising wells from production into hard aquifers, is characterized in that, in order to increase drainage efficiency, the rising wells drill into the group and simultaneously drill the group of rising wells and drill into the mold from the downhole well. in water digging out the rock, followed by the development of torpedoing aquatic and water-absorbing rocks with the formation of zones of continuous fracture and are connected, rising wells with descending ones to form a single closed drainage system, Sources of information taken into account during the examination 6 1.
