Spivakovsk'yj O. The development methods of estimation and ensuring of explosion safety of use of electric power at collieries' deadlock developments.

The dissertation is devoted to development of the methods of explosion safety evaluation at collieries' deadlock developments for wants of use in them an electrical energy. The mathematical model explained shaping process of air-methane mixture explosions' intensity an collieries' deadlock developments from frequency and duration of an electrical source of fire emerging, the protection reliability, explosion protection (EP), protective grounding, system of air monitoring (AMS), terms of their preventive maintenance, frequency if dangerous environment occurring and duration of its existing are obtained.The computing programs for solving these problems are created. The "Methods of explosion safety evaluation at collieries' deadlock developments under conditions of the electric equipment complexes operating in them" , based on the above mathematical model are developed. The work outcomes are tested at mine "Krasnoarmeyskaja zapadnaja №1" of "Donugol" enterprise.
