Abstract

The invention relates to the mining industry and can be used for the remediation of the surface areas of the zones of rockfall. The goal is to increase the safety of reclamation works while reducing labor costs. Preliminary conduct storage of rock and fertile rocks when they are excavated within the boundaries of the zone of collapse with the formation of the developed space before the start of underground mining of the mineral. At the same time, the storage of rocks leads to the developed space with their subsequent overlapping by a layer of stored fertile rocks and the formation of a single bulk mass. The collapse zone is filled as the mineral is mined by sinking a bulk mass into it. The dumping of rocks on an undeveloped stable base eliminates the possibility of the occurrence of mass deformations and ensures the safety of work. 1 il. w ё

Description

The invention relates to the mining industry and can be used for the remediation of the surface areas of the zones of rockfall.

The aim of the invention is to improve the safety of remediation work while reducing labor costs.

The drawing shows the scheme of the proposed method.

Before the beginning of the underground mining of mineral reserves 1 from the territory that falls into the zone of underworking and collapse of the massif, the fertile minerals suitable for recultivation of rocks 2 and

store them outside the specified zone. Then, from the rocks, delivered by motor transport, in the resulting developed space, layer 3 is filled with a power corresponding to the volume of the subsequent collapse. The dumping of rocks on an untreated, stable foundation eliminates the possibility of an array deformation and ensures safety of work. The depth of the collapse zone is established by analogy with the neighboring collapsed areas. After that, the layer of rock is overlapped with a layer 4 of fertile rocks suitable for recultivation from storage depots 2 with the formation of a single bulk massif.

The subsequent excavation of the mineral is accompanied by the collapse of rocks and backfilling of the zone of collapse by subsidence of the bulk mass, which leads to the leveling of the earth's surface. After reclamation of the area of the collapse after mining of mineral reserves, only a clean planning of the surface is required.

Thus, the proposed method makes it possible to create safe conditions for dumping rocks within the boundaries of the zones of collapse, to reduce the duration of their recultivation period and to eliminate the costs for the delivery of rocks suitable for recultivation. In addition, the possibility of accumulating water in the underworked territories and the danger of its breakthrough into mine workings is eliminated.

Invention Formula The method of reclamation of the areas of the collapse zones, including preliminary the storage of rock and fertile rocks and the subsequent backfilling of the zone of collapse from the underground mining of minerals with the overlapping of rocks by fertile rocks, characterized in that, in order to improve the safety of reclamation works while reducing labor costs, the storage of fertile rocks is carried out when they are excavated within the formation of a goaf before the beginning of the underground mining of a mineral, while storing rocks lead to the go followed by their overlapping layer impounded fertile species and the formation of bulk single array, and caving zone filling is produced as t mineral mining subsidence in it the bulk of the array.
