METHOD FOR REMOVAL FIELD PREPARATION IN CASE OF CHAMBER-COLUMNAR EXCAVATION SYSTEM Russian patent published in 2004 - IPC

Abstract RU 2229599 C1

FIELD: mining industry. SUBSTANCE: removal field is separated on two sections with a solid block between them. Preparation of each section is performed separately with use of isolated aeration plans. After sections preparation they are connected with each other on a flank of removal field by connecting opposite faces. Output flow from lower section is taken away along excavations of upper section. Size of solid block fall may be picked equal to width of removed block. Isolated aeration of each section is performed by means of delivery of fresh air from air-supplying excavation into dead-end excavations along ventilation pipes by means of local aeration and output flow taking away ventilators. EFFECT: high effectiveness and reliability of removal field aeration on gas layers as in process of its preparation, as in later stages during blocks removal due to lowered air leaks. 3 cl, 3 dwg
