ethod of mine working // 2624491
FIELD: mining engineering.SUBSTANCE: method consists of multipoint impact on the free surface of the face by the executive bodies driven by external energy sources, giving the central executive body the direction of movement of the combine with the subsequent activation of the peripheral executive bodies and their movement along the trajectory of the epicycloid. At the same time, a shock-shearing effect of a rock-destroying tool by means of generators of mechanical impulses is carried out on the free face by applying prolonged shock loads with a successive step-by-step displacement along the entire surface of the face section.EFFECT: expanding the use of mechanical impact and force to destroy strong rocks, the possibility of changing the direction of mining workings, especially in difficult mining and geological conditions, reducing energy intensity, improving the working conditions of maintenance personnel.2 dwg

ethod of production by impact cutting and impact cutting loading machine for method implementation // 2563467
FIELD: oil and gas industry.SUBSTANCE: impact guiding part is installed. Two ends of the impact guiding part are fitted with impact heads or one end of the impact guiding part is fitted with the impact head, and another end is fitted with the counterbalance. The impact guiding part is installed in the guiding device, the power impact part is installed. The power impact part is installed in the impact actuating unit. The guiding device and the impact actuating unit are integrated with formation of the reciprocating impact part; the power impact part puts the impact guiding part into reciprocating movement. The impact guiding part puts in action impact heads / impact head for impact effect on a coal or rock wall for material crushing; the frame is installed. The frame is fitted or not fitted with the lifting device. The reciprocating impact part is installed on the frame or on the lifting device; the frame is installed on the housing of the machine, or the frame and the lifting device are integrated and installed on the machine housing, the mobile part is installed. The mobile part is installed in the lower part of the machine housing. The mobile part puts the machine housing in motion; the machine housing supports impact heads / impact head for impact effect in a reciprocating manner for material crushing. The impact cutting loading machine contains: the machine housing, the mobile part and the reciprocating impact part. The reciprocating impact part contains the guiding device and the impact actuating unit. The guiding device contains the impact guiding part; meanwhile the reciprocating impact part also contains the impact head, two ends of the impact guiding part have impact heads, or one end of the impact guiding part has the impact head, and another end has the counterbalance; and the impact actuating unit contains the power impact part; the power impact part puts in action impact heads / impact head for execution of reciprocating motion; the impact guiding part puts in action impact heads / impact head for impact effect on a coal or rock wall with material crushing. The machine housing contains a frame and has or has no lifting device, and the reciprocating impact part is installed on the frame; or, when the machine housing has a lifting device, the reciprocating impact part is installed on the lifting device. The lifting device is installed on the frame, and the mobile part is installed in the lower part of the machine housing and puts in motion the machine housing.EFFECT: mining efficiency improvement.29 cl, 128 dwg

ine rock sample obtaining device // 2452932
FIELD: mining.SUBSTANCE: device includes elongated guide, vibrating disc cutter installed for straight-line movement along the guide; and erection device for location and retention of elongated guide in the required place relative to the nearest surface of rock so that vibrating disc cutter can move along the guide and cut the groove of adjustable width and depth on rock surface.EFFECT: improving the sampling accuracy of mine rock samples from channel with uniform cross section.8 cl, 6 dwg
