| titleOfInvention | Method of forming front relief and draining slits in development workings |
| abstract | METHOD OF FORMING ADVANCED UNLOADING AND DRAINING GASES IN PREPARATORY DEVELOPMENTS, including drilling parallel wells and cutting the coal seam between them, in order to improve the safety of work by moving the stress concentration zone from the target, the training component will be prepared. the process of draining gas from it, at the beginning of drilling one well to the full depth of trimming, and then drilling another well with simultaneous trimming of the coal massif between the wells with the aid of a rotating mechanism, which (p. pivotally attached at one end to the guide, which is placed in the first drilled well, and at the other end - to the drilling rig, the secondary drilling of the second well ... |
