Abstract

The article considers the problem of dust explosion safety in coal mines and analyses the existing methods of coal dust control. Several main directions of coal dust control are proposed, including reduction of dust formation, air cleaning and dust binding with the help of water and special solutions. The results of experimental works aimed at studying the effectiveness of various methods of coal dust control in mine conditions are presented. It is determined that preliminary moistening of coal massif reduces dust formation, and the use of solutions with surfactants increases the efficiency of moistening. It is shown that the efficiency of irrigation systems depends on the parameters of nozzles and the mode of their operation. It is established that the use of pneumohydroirrigation allows to achieve more effective dust deposition. The necessity of development of combined dust suppression systems taking into account specific conditions of each mine is substantiated.
