For decrease in a share of manual skills, increase of productivity on all operations of processing explosive, reductions of number of the workers involved from other sites and restriction of a circle of persons, admitted(allowed) to the reference with explosive on underground mines Mountain Shorie and Khakassias 70-80 years have been developed and introduced circuits complex mechanization of explosive works.
The paper deals with the issues of increasing the efficiency of drilling and blasting operations in difficult mining and technical conditions at underground mines through the use of non-electric blasting initiation means - SINV-SH and vertical concentrated charge stripping technology. The results of research for the mines of the Khakassia Mountain Shoriai are given.
At Siberian mines tests were conducted and commercial development of combined technology of rock mass stripping with the use of vertical concentrated charges (VKZ) and beam borehole charges began.
In the practice of blasting in the mining industry during mining of minerals by underground mining for crushing the rock mass, borehole charges of explosives, as well as borehole and stone (mine) charges located in the chambers, tunnels and mine wells are used. The largest volume of rock mass removal is currently carried out by borehole explosive charges. Mines in Gornaya Shoria, Khakassia and the Urals use the technology of stripping by bundles of parallel-conjugated borehole charges.
Mechanization of blasting operations at underground mines in Gornaya Shoria and Khakassia began in the 1970s using granulated explosives and pneumatic charging equipment. Mines tested charging machines UZS-1500, UZS-6000, UZDM-1, 3MB, ZMBS-1 and ZMBS-2 developed by NIPIGormash company.
At many enterprises, depreciation and amortization of buildings and structures significantly exceeds the standard terms. After the commissioning of new facilities, the old ones are closed, their repair and maintenance are stopped. Buildings fall into an emergency condition with spontaneous collapse of walls and elements of building structures with the possible accidental presence of people in the danger zone. Responsibility for the occurrence and consequences of a hazardous situation is borne by the company in charge of the facility. In order to eliminate the hazardous situation, it is necessary to carry out measures to eliminate the emergency facilities.
