Abstract

The invention relates to mining and m. used in the development of sloping and flat beds. The purpose of the invention is to reduce the volume of mining capital works to involve the discovered mineral reserves in the development. The field is divided into quarry fields 1-3 and involve the primary field 1. The reservoir of the mineral is opened by trenches (T) 5-7 of the outer foundation, split T 8 is carried out and the covering rocks and the mineral layer are mined laying the underlying rocks into the inner dump, the rocks of the upper benches - into the outer dump 16. Through the adjacent career field 2, after working out the section 17, the floor 1 carries T 18 with the adjoining of its outer side 19 to the working side 20 floor 1. On board the passing along the borderfield 7 2 trenches create front mining (GRF), and combined it with GRF floor 1. Next fulfill field 2 prodviganiem GRF GRF prodvngani transverse to the floor 1, T poured overburden opposite field 2 form a single GRF. The last one is worked at an angle to the direction of advancement of the FGR floor 1. After each advancement of the FGR floor 2, the transport field is carried out by the magnitude of the excavator block. After the field 1 has been fully developed, the adjacent field 2 is similarly worked out. 4 Il. (Oh (L

The invention relates to mining and can be used in the development of seams of a mineral inclined and flat bedding.

The purpose of the invention is to reduce the volume of urban-capital works to involve the discovered mineral reserves in the development.

FIG. 1 - 3 the scheme of opening and preparation of career fields is shown; in fig. 4 ssma mining management.

The field is cut into quarry fields 1, 2, and 3. The primary career field 1 is involved in the mining operation. A section 4 of the useful1 0 fossil is opened up in the opening 5–7 of the fossil, a split is made by the 8, 7 mineral fossil parallel inlets 10-12, respectively, along the dip of the reservoir with the laying of rocks below the bottom, it is only 13 into the internal dump 14 and the rocks of the advanced ledges 15 are transported into the dump 16.

After the adjacent career field after the development of the section 17 of the prime career floor, transshipment 18 is conducted with its BueuiHero bead 19 adjoining to the working side 20 of the priority career floor. Gtrichhem TpaiinieK) passes with the foundation of its bottom above the roof of the mineral layer. In the subsequent period, the adjacent career no is being developed, ie, from the open side of the 21 primary career floor. At the same time, the rocks of the advanced ledges of the adjacent quarry floor L involve the development of the said trench from the outside of the bed as they move the front of the work and transport them along the same to the external dump. The mining and covered front of mining operations by the underlying crowd of rocks are combined with the mining and mining front of mining operations of the underlying formation of the adjacent quarry floor and form a single front of mining operations. In the developed space of the adjacent open-pit floor, after each advance of the work on the formation strike to the length of the excavator block from the axis of the existing trench, the exit trench 22 and, as the work front on the formation of the reservoir 23 stretches across the front of the mining front, move the floor, on the opposite flank of the quarry floor, reduce the mining front 24, repay the exit trenches of the primary career floor and form a single mining front 25, which move at an angle to detecting podviganiya front of mining operations priority career floor.

For this purpose, trenches are poured over the overburden in one place or along the entire length. As a result, it is possible

for excavator or bulldozer dumping on the roof of open pit dumps of the underlying crowd. Known methods using known means create an excavator | 1 st or dozer blade.

After refining the first career floor, the operations of opening and testing each subsequent career floor are repeated.

Invention Formula The method of open development of reservoir deposits of mineral resources, including the division of the field into quarry floors and the penetration of transport passages between them, opening the primary and adjacent quarry fields with external laying trenches, cutting between them of the transshipment, forming a mining front priority career floor and the development of overburden ledges and minerals by excavator blocks, the separate movement of rocks of the upper ledges to the outer heap, and lower rocks stupas — into the internal dump, backfilling of the transport trench opposite to the adjacent career field, and engaging in the development of the specified adjacent career floor, characterized in that, with the aim of reducing the mining capital works in the development of the discovered mineral reserves into the development, after mining the section of the primary career floor through the adjacent career field, the transport trench passes with the adjoining of its transport lanes to the working area of the upper ledges, and passing along the border with an adjacent career field create a mining front and merge it with the mining career of a primary career field, then work off an adjacent career field with moving the specified mining front across the mining career of the primary career floor, then form a single front the mining operations of the above-mentioned primary and adjacent career fields and work it at an angle to the direction of the mining front's advancement of the primary career floor, after this dogo podviganiya front mining adjacent quarry floor by an amount excavating unit length within the boundaries of said adjacent floor career carried out additional transport transcheyu then ate full mining career priority field for the preparation and testing of each subsequent repeated quarry floor.
