Purpose of the development: For the extraction of coal and rock from thin seams.

Recommended application field: Mining industry.

Advantages over analogues: Reduces the costs of maintaining mine workings, creating conditions for their re-use. The development of reserves of substandard capacity, which will increase the service life of mines.

The development stage readiness: Tested experimental exploitation order

Technical and economic effect: 1. The transition to selective technology will allow: - reduce the prime cost of coal mining by 10-13%; - additionally remove more than 340 million tons of coal from the bowels; 2. Formation of a new coal mining philosophy: - the breed remains in the mine; - coal with ash content up to 18% without enrichment is sent to the consumer. 3. The calorific value of coal, which is released from the mine, rises by 30% - from 4000 to 5760 Kcal / kg.

Description of the development:
()
The excavation of coal and rock is carried out separately, for two or one pass of the combine. Simultaneously with the extraction of the rock, it is laid in the developed space. The technology is implemented with various development systems: poles, solid, combined. Elements of the technology were tested at the mines of the Western Donbass and the Lviv-Volyn basin. As a result of the tests, the output technical requirements for the creation of a reclaiming-packing complex of machines for separate excavation of coal and prisychnyh rocks were developed.
