Name of the invention Acquisition method and device 3 by rock cutting and open pit mining, person who performs correction Relationship to the case: Patent applicant Hoheger, Gottsfried 4. Agent 1-1-20-5 Toranomon, Minato-ku, Tokyo 105, subject to amendment (1. Name of the invention (2) Full text of the specification 6. Contents of correction (1. The name of the invention has been changed to “Method and device for obtaining rock by cutting and open-pit mining.”) Correct.

Specification For the implementation of the method In particular, the present invention is capable of blowing up a battery (excavated object) without an excavator or a loading device. Relating to a method of obtaining open-pit coal, crushed stone or ore by. others For this purpose, a device to collect the blasted deposits and a collision buffer are required.

, in such an acquisition method, the debris deposit from the blast is received by the conveying device. In particular, in the method of the present invention, the method is defined by the method. In order to make this possible, a collection-buffer device must be attached to the conveyance device as an auxiliary device. Is required.

An angle that does not deviate from vertically or vertically when blasting batteries with stairs or layer structure has been known to poll and blow up. Debris deposited on the stairwell after blasting The pieces are lifted into a conveying device in the form of a shovel by an excavating or loading device. .

This is done by using a thrust device to move the layered or step-like deposits from the blast down to the shaft. The same applies to the drop structure that allows the object to fall.

Even in the case of a funnel structure, which is not often used, the excavation or loading equipment can be omitted; The deposit can also be brought to the conveying device, but this requires The advantageous battery detonation is generally not available.

In open-pit coal mining, if the coal is easily blown up, the application of the present invention is also applicable to the excavation. Eliminating the need for equipment. In this case, the particularly large capital and operating costs are 1 Savings can be made depending on the requirements of heavy equipment.

Current open pit acquisition methods involve blasted or disintegrated piles of batteries. Transferring objects to a conveyor device, not immediately and without intermediate operations This is known to occur due to the collection-impact damping device according to the present invention. is directly possible. Telescoping crash buffers - for example, AT-PS No. 377585, this device is known for its loading into a conveying device. There are defects and it cannot be put into practical use.

The object of the present invention is to eliminate the need for lifting work of excavation equipment or loading equipment, and thus The battery must be removed so that the necessary equipment can immediately receive the blown battery. The purpose is to carry out the explosion of

According to the invention, this problem is solved by Blow up the battery that is present along with the stepped opening by tilting it against the mineshaft. and that the collection-buffer device according to the two preferred embodiments on the slope formed by the blast itself, damaging equipment and conveyance equipment. The solution is to collect the problem without any problems.

The first embodiment is a self-supporting articulating link buffer.

The advantage in this case is that the transport device, especially the dump truck, occupies only a small amount of installation space. It is just something that is done.

The second embodiment as a flat-plate shear damper is advantageous in construction. It is transportation This is because there is no need to change the structure of the device, such as a dump truck. child With this buffering, particularly high collision energies can be absorbed.

Another difference with traditional open-pit mining methods is that the entire battery is not blown up at once. Instead, the sections corresponding to the receiving capacity of the transport device are blown up one by one. Battery The detonation of each category is caused by the amount of explosives limited by tamping. Ru.

The long hole poling of the lying battery to receive the explosives is carried out on the upper shaft. It will be carried out at
