The greatest destruction of the soil cover and natural landscapes occurs during the development of the field by open pit mining. As a result of the development of the field, a complete change in the relief occurs, disruption of water and air balances, which leads to disruption of the ecosystem as a whole. To stabilize the state of the environment, it is necessary to implement a set of environmental, economic and social measures to restore environmental components. In this case, it is necessary to take into account...

In the development of mineral deposits by the underground method, geomechanical processes are manifested, which significantly affect the quality of ore, the cost of production and the safety of mining operations. Insufficiently valid choice of geomechanical steady spans of outcrops can lead to a sudden collapse and formation in clearing workings, thereby reducing the safety of mining. The work provides a definition of sustainable roof exposures of the clearing workings according to the method of S.V. Vetrov for fr...
