INVESTIGATION OF THE EFFECT OF DISJUNCTIVE DISORDERS ON THE CONDITION OF THE ROCK MASS IN THE VICINITY OF THE PREPARATORY MINE
Abstract
The Kuznetsk coal basin is characterized by very high tectonic disturbance. The impact of disjunctive disturbances on the productivity and safety of underground mining operations is caused by the formation of hazardous zones, which are characterized by increased release of methane, water, unstable roof rocks, the edge of the seam, a decrease in the strength of coal and wall rocks, as well as an increase in their fracturing. Coal squeezing, swelling of the rocks of the preparatory workings, intensive formation of "sandwiches" and "domes" of roof rocks, etc. are often observed. In this regard, additional labor and material costs associated with the implementation of measures to ensure the stability of roof rocks and heterogeneous pillars increase. The safety of mining operations in zones of influence of geological faults of the rupture type is provided for by the development of special projects or measures, which are regulated by the “Regulations on the procedure and control of safe mining operations in hazardous zones”.
