THE HYDRAULIC FACTORS SUBSTANTIATION AT STEEP COAL SEAMS’ DEVELOPMENT WITH HYDROIMPULSIVE INSTALLATION
Journal Title: Вестник научного центра по безопасности работ в угольной промышленности - Year 2018, Vol 0, Issue 3
Abstract
The paper presents the hydraulic factors substantiation at steep coal seams development with hydroimpulsive installation (HII), the required pressure at the outlet of hydroimpulsive installation is found, analytical expression for determination HII outlet required pressure adequacy check is fulfi lled, installation pressure required to crush the coal massif with the pulse jet to carry on extraction and preparation works when coal resists cutting is found, dependence is obtained to determine the necessary force to crush the coal seam with hydroimpulsive installation, determination of the required pulse jet pressure at the outlet of hydroimpulsive installation for preparation and extraction works is done. The materials of this research will be used both to compile a mathematical model of the interaction process between the installation hydroimpulsive jet and the coal massif to be crushed and to design hydroimpulsive installations aimed to develop steep coal seams.
