The method of preparation of gas-saturated layer

 

(57) Abstract:

The invention relates to mining and can be used in the preparation of gas-saturated reservoir to the development of long poles. The method of preparation of gas-saturated layer includes mine sinking combine with the preliminary degassing of the face. Degassing is carried out develop in the direction of two or more faces, and then are released by the harvester. The method reduces the downtime in the preparation of gas-saturated layer. 1 Il.

The invention relates to the mining industry and can be used for the preparation of gas-saturated layer to the subsequent development of long posts.

The known method of preparing gas-saturated reservoir, including the use of blast hole drilling downhole, the loading holes explosive materials, blasting slaughter, schreberiana winch with bucket repulsed weight of the formulation (see Mountain encyclopedia /CH. editor E. A. Kozlovsky - M: Owls. Encyclopedia, 1989, volume 4, pages 140-142).

The disadvantage of this method is limited mechanization of the processes of penetration, high complexity, the occurrence of negative effects on seismic waves in the gas-saturated reservoir, including a preliminary degassing of the face (for example, by drilling or contained blasting) with subsequent sinking of preparatory development using the harvester (see Mountain encyclopedia /CH. editor E. A. Kozlovsky - M: Owls. Encyclopedia 1989, volume 2, pages 206-207, volume 4, pages 267-268).

A disadvantage of the known technical solution is that during the degassing of the face of the harvester should be driven away and forced to stand, and during the sinking develop harvester equipment for the production of degassing cannot be used and it is idle. Length degassed part of the face may not be a big haul, so you constantly have to fend off the combine for installation in the mine equipment for degassing, on the contrary, to remove the equipment for decontamination and to carry out the driving of the developing harvester on the length of degassed part of the face. It need to constantly repeat, i.e. we have to perform many operations on moving equipment and harvesters, not associated with penetration openings. Creates a low level of use of technology.

The purpose of the invention is the reduction of downtime in the preparation of gas-saturated layer.

The drawing shows the method of preparation of gas-saturated layer (top view), where the diagrams: a - shows the state of completion of the preparatory work at some point in time; b - same, for the next time; numbers denote: 1 - dotted line shows the contours of future treatment developments, 2 - contours of the previously traversed by the harvester development workings, 3 - paths previously made degassing faces preparatory workings, 4 - circuit output, which is the processor, 5 - contours carried out by degassing of two or more faces.

The method of preparation of gas-saturated layer is as follows.

being harvester generation 4 there where previously made degassing faces preparatory workings 3. Then the equipment for degassing move to one of the faces of previous mines 2 and produce the degassing of two or more faces 5. At the same time the harvester performs tunnelling generation 4 where previously made degassing faces preparatory workings 3. Preparatory development 2 and 4 are the harvester so that in future it was possible to carry out the duties workings 1 and to provide a treatment workings 1, for example, transportation of ore, ventilation, a bookmark, and all other processes necessary for the development of gas-saturated layer.

This method of preparation of gas-saturated layer passes the stage of development work at the mine, the First mine of OJSC "Silvinit" on the gas-saturated reservoir In Karnal-lithium compound.

The method of preparation of gas-saturated reservoir, including mine sinking combine with the preliminary degassing of the face, characterized in that the pre-degassing is carried out develop in the direction of two or more faces, and then are released by the harvester.

FIELD: mining industry.

SUBSTANCE: method includes use of screw-drilling machine for driving of several first ventilation shafts in ore body and driving several second shafts, while second and each second shaft crosses, at least, one matching first shaft, forming first support walls, supporting ceiling. First supporting ceilings consist of ore body zones between neighboring second shafts, each first support wall has portion of at least one first shaft, passing horizontally through it. Horizontal channels are formed, each of which is placed transversely to matching second shaft between appropriate portions of first shaft, formed in adjacent support walls, for forming of group of continuous ventilation shafts. Second shafts are filled for forming second supporting walls, supporting well ceiling, and first supporting walls are extracted. First ventilation shafts can be made parallel to each other. Second shafts may be directed perpendicularly relatively to first ventilation shafts. In ore body air-outlet and air-inlet ventilation mines can be formed, placed at distance from each other along horizontal line, while first or each first ventilation shaft passes through portion of ore body between air-inlet and air-outlet ventilation mines. Driving of second or each second shaft can be performed by cutting machine, or by drilling or explosive mining.
