Open pit coal mine self-moving-type continuous coal mining and loading equipment and arrangement method thereof

Abstract

The invention discloses open pit coal mine self-moving-type continuous coal mining and loading equipment and an arrangement method thereof. The open pit coal mine self-moving-type continuous coal mining and loading equipment is characterized in that the open pit coal mine self-moving-type continuous coal mining and loading equipment comprises a caterpillar truck, a coal falling machine, two cutting rollers and a transporting chain; the two cutting rollers are concentratedly arranged in the middle of the coal falling machine, connected with the coal falling machine, and arranged in a vertical mode; a certain distance is formed between the end faces, close to the coal wall side, of the two cutting rollers, and a mined coal wall is divided into a step shape; the coal falling machine is located on the caterpillar truck and is in rigid connection with the caterpillar truck. The transporting chain is located on the lower portion of the coal falling machine and is in rigid connection with thecoal falling machine. A working face is mainly formed by arranging a self-moving-type mining and loading machine, a working face transferring belt and a working face rubber belt conveyor. The open pit mine self-moving-type mining and loading machine can achieve continuous mining and loading work of coal seams of different hardness. Technological arrangement is conducted in single-step arrangementand multi-step arrangement modes according to the thicknesses of the coal seams, and the equipment and the arrangement method can adapt to the coal seams of different thicknesses and meanwhile have high adaptability to different complex environments under open pits.

Description

technical field [0001] The invention relates to an open-pit coal mine self-moving continuous coal mining equipment and an arrangement method thereof, belonging to the technical field of mining. Background technique [0002] At present, the main mining technologies adopted in my country's open-pit coal mines are discontinuous technology, semi-continuous technology, and continuous technology. When the conditions at the bottom of the open-pit coal mine are complex, such as areas with a lot of water and fire, it is extremely inconvenient to use the intermittent process for mining and transportation, and the production stability is poor. In addition, when the intermittent process and the semi-continuous process are used, a large amount of dust will be generated during the blasting process, causing environmental pollution. The continuous process is rarely used in China, mainly because the equipment is complex and expensive. At the same time, the equipment has high requirements fo...

Problems solved by technology

When the bottom of the open-pit coal mine is complex, such as areas with many water and fire areas, it is extremely inconvenient to use the intermittent process for mining and transportation, and the production stability is poor

In addition, when the intermittent process and the semi-continuous process are used, a large amount of dust will be generated during the blasting process, causing environmental pollution.

The continuous process is rarely used in China, the main reason is that the equipment is complex and expensive, and the equipment has high requirements for the hardness of rock or coal seam, and the adaptability to hard rock or coal seam is poor
