Yordanov I. Higher safety of the electric power application on mines gas and dust hazardous by use of ultrafast switches on an electrohydraulic basis

In the work proposed and analyzed in detail the idea of safe use of electricity in coal mines dangerous on gas or dust, provided that the relief and emergency equipment item fire before them the environment solely due to the performance of the protective device without any additional technical solutions. Performed research allowed to substantiate the requirements for ultrafast protective equipment designed for operation in coal mines, dangerous for gas or dust, as well as at other enterprises of the industry. The concept of development of magnetic station of new generation with the changeable structure providing safe application of the electric power on a concrete site, and consequently, and on all coal mine gas and dust hazardous, excluding possibility of environment ignition from a source of electric energy in emergency operation, at the expense of a complete set of this station protection devices of ultrafast shutdown on an electrohydraulic basis is developed.
