WAYS OF IMPROVEMENT OF TECHNOLOGIES FOR MINING

Over the past 5 years, the average monthly speed of horizontal workings at non-ferrous mines has increased by 37%, rising by 32%, and the productivity of sinkers has increased by 20%. With the increase in the depth of development and mining pressure, the labor intensity and volume of mining capital and preparatory work has increased, and in some cases, the time spent working out takes more than 60% of the total time for the construction of mines and new horizons. In this regard, there is a need to organize high-speed workings with the effective use of modern means of mechanization. Recently, non-ferrous metallurgy mines have been equipped with new, more advanced self-propelled drilling, loading and delivery and auxiliary equipment. Using this equipment allows to increase the productivity of tunnellers by 3-4 times with bringing the speed of horizontal capital workings to 200-300 m / month and preparatory rifling workings to 150-250 m / month, while reducing the cost of 1m3 of rock mass by 10-30%. Such speeds allow significantly reducing the time required for preparing the cleaning blocks for excavation.
