AERODYNAMICS EXCAVATION FIELDS A POWERFUL SHALLOW SEAMS
The Strict observance of technological discipline, reducing operational losses and the selection of the optimal mode of ventilation was essential in connection with the development and implementation of new technologies and application of modern highly productive equipment for underground mining of thick flat coal seams. The article considers the scheme of ventilation of viamach-tion fields in the powerful shallow aquifer with the aim to study the aerodynamics of the extraction fields to determine the effect of schemes, methods and parameters of ventilation, wieloch-tion of the fields on the distribution of air leakage in the goaf.
