(54) KO fflLEKC for the construction of mining in soft rocks (57) The invention relates to mining and b. used for excavation of vertical mine workings. The goal is to increase the rate of penetration. The bucket-type rock loading machine t is made with a vertical movement mechanism in the form of a hydraulic cylinder (HD) 9 connected to a central tube, which is made telescopic from the clips 10 and 12. The inner cage 10 has a longitudinal groove and is hingedly connected to the 8-D rod 9. The cylinder HD 9 is connected by flanges 14 and 15 to the outside f.

A clip 12, which is rigidly connected to the support frame 2 and has a key 13 placed in the groove of the clip 10. with the pillars 3, they are braced against the lining of the trunk, and the holder 10 by means of the HD 9 - into the rock face. When introducing the working body of the machine 1 is uniform

load distribution, and the interaction of the key 13 with the groove of the yoke 10 does not allow transmission of torque from the rotation of the machine 1 around the axis. The machine 1 begins the excavation of the rock. After this, the formwork 5 with frame 2 is detached from the lining and moved to a new entry. Over the course of the excavation period, the holder 10 is moved by the rod 8 in the holder 12 and kept in contact with the bottom of the breed. 2 Il.

The complex belongs to the mountain

case and can be used for sinking vertical mine workings.

The aim of the invention is to increase the penetration rate.

Fig, 1 shows the device section; in fig. 2 — node I in FIG. one.

The device comprises a bucket-type rock-loading machine 1, a support frame 2 consisting of radially arranged sectional elements connected to one end, the other end of each of which is connected through vertical uprights 3 and ball joints 4 with the formwork 5 and spreads through the mechanism 6 The trunk support 7, the support frame through the rod 8 of the vertical movement mechanism, made in the form of a hydraulic jack 9, is connected to the central tube consisting of the inner race 10 with the groove 11, the outer race 12 with the key 13 and the flange joint 14 and 15 minutes, one of the flanges, such as 15, and a detachable hinge, and through movement of hydraulic cylinders 16 is interconnected with the knife-seal 17.

The complex works as follows.

After the installation of the complex in the trunk, the construction of support 7 of monolithic concrete to the height of the formwork 5 and the spreading of the support frame by the mechanism 6 of the spread in the support 7 begin using the rock-loading machine 1 to excavate the rock, leaving the berm a.

The radially arranged, joined elements of the support frame 2 are made, for example of a box section, and are connected at one end and the other end

Each of the elements is associated with the formwork 5. Through the vertical pillars 3 and the hinges 4, by means of the thrust mechanism, they spread into the support 7 of the barrel, the I support frame through the hydraulic sleeves 9 of the inner sleeve 10 of the central tube spreads into the rock. At the same time, when the working body of the rock-loading machine 1 is introduced, the load is evenly distributed, and the interaction of the removable tongue 13 on the outer cage 12 with the groove 11 on the inner cage 10 of the central tube does not allow the torque to be transmitted from turning

 rock loading machine 1 around the axis.

After the draw completely turn on the jacks 16

5, the pedigree berm is cut off with a knife-compactor 17, and at the same time the walls of the trunk are compacted, which ensures their stability without installing a temporary lining, which

Q is usually set in soft rocks. Then the formwork 5 is removed from the concrete lining 7, the thrust mechanism 6 is removed into the support and, under its own weight, the formwork 5 together with the supporting frame 2 is moved to

the next entry, lower the knife-setter 17, set the formwork to the working position and center. And over the whole time

the recesses of the rock core, the inner race 10, periodically move the outer race 12 with the stem 8 of the hydraulic jack 9, keep the bottom in contact with the rock and press into it no less than 200-400 mm depending on the strength of the rocks.

After centering the formwork 5 and spreading the support frame 2 into the lining 7 by the mechanism 6, the cycle is repeated.

Claims (1)

Invention Formula The complex for the construction of mining workings in soft rocks, including a bucket-type rock-loading machine with a vertical movement mechanism, a support frame, a central pipe, a formwork for the erection of lining, 70-12, distinguished by the fact that, in order to increase the penetration rate, it is equipped with vertical posts with ball joints in the upper part, the peripheral ends of the supporting frame elements are connected with the formwork with ball joints of vertical struts, the mechanism of vertical movement is designed as a hydraulic jack, while the central tube made of telescopic two cages, the inner cage has a longitudinal groove and is pivotally connected to the hydraulic cylinder stem, the hydraulic cylinder cylinder is connected to the outer casing by means of flanges, and cage rigidly coupled to the support frame and the key is disposed in a groove of the inner ring.
