Abstract

The invention relates to a high pressure water jet cutting drum coal dropping double power shearer. The invention is characterized in that the shearer comprises a drum shearer and a high pressure water jet cutting device; wherein the high pressure water jet cutting device is arranged at the front end and rear end of the drum of drum shearer body. The shearer can obviously improve coal dropping block coal yield, greatly reduces coal dust generation rate and reduces hazard of coal dust explosion and harm of dust lung, thus having great economic benefit and social benefit. The shearer can be applicable to coal mine which generally adopts drum shearer.

Description

technical field [0001] The invention relates to the field of coal mining in coal mines, in particular to a high-pressure water jet slit drum coal-dropping dual-power shearer that significantly increases the lump coal rate and greatly reduces coal dust. Background technique [0002] The world's three basic energy sources come from coal, oil and natural gas. Coal is the most abundant solid fossil fuel in the world, and it is distributed in countries all over the world, such as China, North America, Australia, South Africa, Russia, Europe and so on. With the rapid development of science and technology in today's world, especially coal mining machinery and equipment have entered the large-scale comprehensive coal mining mechanized equipment that operates automatically, jointly and efficiently. At present, coal mining in the world mainly adopts a comprehensive set of coal mining equipment such as drum shearer, scraper conveyor and hydraulic support, which greatly improves coal ...
