METHOD FOR DEVELOPMENT OF A FLAT COAL BED Russian patent published in 2020 - IPC E21C41/18 E21F11/00 

FIELD: mining.

SUBSTANCE: invention relates to mining, to preparation and development of mine field of gently sloping coal bed. Method for development of a shallow coal bed includes preparation of a mining pillar by carrying out several drifts along each long side with cutting of the mounting chamber along the short side of the column and installation of a cleaning mechanized complex in it, development of extraction pillar by mechanized complex at movement of mining face by reverse stroke, transportation of coal and ventilation of mining face due to general mine depression. With the drifts from one side of the extraction pillar and no later than the field drift is carried out – rescue in the bed rock from the same side and throughout the length of the pillar. Emergency and rescue mine working is beaten with each drift, located on one side of pillar, with diagonal junctions – exploratory evacuation workings, and uniformly and in turn distributing them along pillar length. Movement of air jet in rescue operation is received from center to flank.

EFFECT: invention makes it possible to increase safety of mining operations during coal mining from gently sloping beds and efficiency of mine rescue operations in case of technogenic accident.
