(54) METHOD FOR DEVELOPING POWERFUL, RAPPED PLASTS OF MINERAL RESOURCES

one

The invention relates to the mining industry and can be used in the development of thick steep mineral deposits, mainly coal.

There is a method of developing powerful steep seams of minerals, which includes carrying out preparatory workings and mining the reservoir with chambers with the laying of the developed space {}.

There is also known a method of developing powerful steep seams of minerals, including carrying out field haulage and ventilation shchrek, kverschlagov and rifled workings and working out the reservoir chambers with preliminary excavation of the primary chambers through one with the laying of their depleted space hardening mixture and subsequent excavation of the secondary chambers with the laying of their depleted spaces of waste rock 2.

However, both of these methods are characterized by insufficient efficiency and safety of development. 5 The aim of the invention is to eliminate this drawback.

The goal is achieved by firstly removing the layer from the roof of the reservoir along its strike in each chamber, and then working out the remaining array of mineral camera in the direction from the roof of the reservoir to the soil by successively removing the shavings of the mineral fossil after the rise. at the same time across the entire width of the chamber, the preparatory and cleaning work spreading out in time and space so that within one chamber only one of the

10 specified operations.

FIG. I presents the development scheme in the plane of the reservoir; in fig. 2 - development scheme across the strike.

The method is as follows. Powerful steep seam 1 mineral

15 are prepared for the development by field haulage and ventilation drifts, square 2 and cut openings 3. The reservoir development is carried out by chambers with preliminary excavation of primary chambers 4 with a longitudinal axis to the formation dip with laying the developed space with a hardening mixture 5. Then secondary chambers 6 are dredged 6 with laying the waste space empty breed 7. In each

Form ul about the invention A method of developing powerful steep strata of minerals, including carrying out field haulage and ventilation drifts, crosshairs and rifled workings and mining the stratum with chambers with preliminary excavation of the primary chambers through one with the laying of their worked out space with a hardening mixture and subsequent excavation of the secondary chambers with the mortgage · What is their waste space waste rock, characterized in that, in order to increase the efficiency and safety of development, in each chamber in the first place a layer is excavated at the formation roof along its strike, and then the remaining array of the mineral chamber is worked out in the direction from the formation roof to the soil by successively removing the mineral chips at the uprising and falling of the formation simultaneously over the entire width of the chamber, while the preparatory and cleaning works are dispersed over time and space so that within one camera only one of these operations is performed.
