Abstract

The invention relates to the mining industry and can be used in ajar mining of watered mineral deposits. The purpose of the invention is to reduce the impact on the ecological balance of adjacent lands by reducing drained areas and their pollution while reducing environmental costs. The overburden rocks are poured into the developed space by crests, ponds are formed between crests. Combs form multi-layered. Into the ridge closest to the working zone of the ridge, solid rocks are poured, and waterproof rocks are deposited on the far slope. As the rocks develop, a new pond is formed. A pump is installed on each ridge, with which adjacent ponds are connected. The pond nearest to the working area is additionally connected to the working area. Pumped water from the working area in the specified pond. The water level in each pond is kept below the water level in the previous one by pumping water. 3 hp f-ly.

Description

The invention relates to the mining industry and can be used in the open pit mining of mineral deposits.

The purpose of the invention is to reduce the impact on the ecological balance of adjacent lands by reducing drained areas and their pollution while reducing environmental costs.

The method is carried out as follows.

The mining of overburden minerals lead ledges. The overburden rocks are poured into the developed space, along the ledges of the ridges, to form closed ponds. Gre & nor form multi-layered. The strongest overburden is poured into the ridge closest to the working area to form the main prism carrier. On the far,. impermeable differences of overburden rocks are poured from the working area to the slope, which leads to shielding of the ridge rocks. The waterproof part is covered with weak differences of overburden. After the bead is formed, a pump is placed on it, the newly formed pond is connected to the working area of the pit by means of a pump, and water is pumped from the working area of the pit to the pond. As the mining operations are removed, another ridge is poured, forming another pond. Moreover, the pumps on the ridges are arranged in a staggered order relatively earlier installed on the previous ridges. Low-pressure low-pressure pumps are used to pump water. Water level in each pond

maintain less water in the previous one by pumping water,. Invention Formula . 1. C (dewate of the development of flooded deposits, including the mining of working horizons, dumping of overburden into the developed space with ridges along the mining front with the formation of a space between ridges, mining in the working area, characterized in that, in order to reduce the impact on the ecological balance of the adjacent lands by reducing the drained areas and their pollution while reducing the cost of the ecology, shield the inner surface of the ridges, set on each pour back pump ridge pumped out five From the working area into the space between the ridges to the dumping of the next ridge with the formation of a pond, after which the operations on the formation of the pond are repeated in a similar order, with the water level in each pond being maintained below the level of the previous pond. 2. A method according to claim 1, characterized in that the shielding of the surface is performed by dumping the impermeable rock to the slope of the ridge farthest from the working area. 3. A method according to claim 1, characterized in that low-pressure pumps are used to pump water and maintain the level in the ponds. 4. A method according to claim 1, characterized in that the pumps are arranged in a checkerboard pattern.
