METHOD OF COMBINED DEVELOPMENT OF FLAT SEAMS OF COAL DEPOSITS

摘要

FIELD: mining operations.;SUBSTANCE: invention relates to mining, in particular to the combined development of flat seams of coal deposits. Simultaneously with the drilling and development workings at the border of the mine field the transport working is passed, from which the development workings are passed, contouring the extraction column with the counter headways, and also a mounting chamber is prepared for the mechanized complex, in which it is delivered and assembled. The extraction of column is carried out after connecting the development workings. Other columns are prepared in a similar technology.;EFFECT: reducing the time gap between the open and underground mining operations, as well as reduction of operational losses of coal.;1 dwg
