Abstract

FIELD OF THE INVENTION The invention relates to the mining industry, namely to the underground mining of wall stones. The goal is to increase productivity. During the extraction by the stone-cutting wall stone, the wall being developed is divided into several parts (preliminary application of scratches). At the same time, cuts of various functional purposes are made on two parts of the wall. Then, saw cuts are made on the first part, performed earlier on the second part. The cuts performed earlier on the first part are made on the last one. In this way, horizontal and vertical cuts can be carried out simultaneously on different parts of the wall, followed by production of back cuts and removal of products. After the stone has been completely removed from the wall, the machine moves and develops the next wall, and the array development process is repeated. 4 il. with co

Description

The invention relates to the mining industry and can be used in the underground mining of wall stone.

The purpose of the invention is to increase productivity.

FIG. 1 shows a stone-cutting machine, working, and the proposed method, a general view, frontal projection; in fig. 2 - the same, top view; in fig. 3 - drawing of the wall being developed, divided into two parts; in fig. 4 - consistently developed walls with the passage of a horizontal shaft, section.

machines (not shown). At the same time, the manipulator 3 performs sawing on another part of the wall, after which the turntable 2 again rotates by 180 ° and makes backing cuts on the second part of the wall, etc.

After removing all the blocks from the first wall, the frame with the help and the stepping mechanism (not shown) is shuffled, one step ahead and the machine begins to develop a second wall with the manipulators. After removing all the blocks from the second wall, the stone-cutting machine moves one step further and the array development process is repeated.

For putting in the sawing backing

Two manipulators 3 and 4 are installed, each 15 bars 10 are preliminarily preparing a niche, the usual ones are equipped with their own turning circle 5, two movable levers 6 and 7, and a bar head 8. The manual 3 has a fixed bar 9 for vertical and horizontal cuts, on the manipulator 4 - bar 10 for backing cuts, as well as a spring-loaded pressure plate 11 for removing blocks cut from the wall 12 being designed.

Stone cutting machine works as follows.

The developed wall is divided into several parts (e.g., by pre-applying a rick on a wall with a pin). The manipulator 3 makes a painting on one part (vertical

in a great way.

With the proposed method, horizontal and vertical cuts can be performed simultaneously on different parts of the wall, followed by removal of the products.

Invention Formula The method of mining wall stones in underground conditions, including the execution of cuts on the wall being developed, characterized in that, in order to increase productivity, the wall being developed is divided into parts, cuts of different functional purpose are made simultaneously in two parts, then on the first and horizontal cuts). Then the portions of the AOR parts are made by sawing, performed by turning the turntable 2 by 180 °, and the manipulator on the second part, and on the second part - In lor 4, backing propi-propyls are performed, performed earlier in the first hour with the selection of the stone and the laying of its nati, and so on until the stenotransporter is completely removed, standing behind the stone-cutting stone. machines (not shown). At the same time, the manipulator 3 performs sawing on another part of the wall, after which the turntable 2 again rotates by 180 ° and makes backing cuts on the second part of the wall, etc. After removing all the blocks from the first wall, the frame with the help and the stepping mechanism (not shown) is shuffled, one step ahead and the machine begins to develop a second wall with the manipulators. After removing all the blocks from the second wall, the stone-cutting machine moves one step further and the array development process is repeated. For putting in the sawing backing bar 10 pre-cooked niche customary 10 pre-cooked niche usual in a great way. With the proposed method, horizontal and vertical cuts can be performed simultaneously on different parts of the wall, followed by removal of the products.
