A mathematical hydraulic support self-tracking model for three-machine cooperative mining is proposed to address low efficiency and difficulties in strategy evaluation of a fully mechanized coal face. The proposed model uses the coordinates and traction speed of the shearer to calculate the frequency of the circular hydraulic support …
In proposed coal-cutting machine, piston forces water through nozzle, expelling pulsed jet that cuts into coal face. Spring-loaded piston reciprocates at end of travel to refill water …
Longwall mining is a highly productive coal mining technique using machines with multiple coal sheers mounted on self-advancing hydraulic ceiling supports. These underground mining machines are massive, about 800 feet in width and 5-10 feet tall. The shearers cut coal from the wall face, allowing it to fall to a conveyor belt for …

Hydraulic mining utilizes the force of water sprayed under high pressure to extract coal. Hydraulic mining utilizes continuous miners to mine entries to gain access to production panels. Once a production panel is established, high-pressure water cannons are used to break the coal off the face.
Our range of mechanical industrial cutting equipment includes electrically powered and track-mounted bolter miners for constructing and securing roadways, continuous miners and borer miners for continuous extraction of coal and soft minerals, boxhole borers for boring circular passages, reef miners for low-profile mining, roadheaders for underground …

In hydraulic coal mining the coal bed is broken down either by means of a high-pressure water jet (5 to 10 meganewtons per sq m), which is formed by monitors, or by means of mechanohydraulic machines (mechanical breakdown of the coal with subsequent washing out by the water). The water is supplied to a stope through pipes from centrifugal pumps.
Pre-driven recovery rooms (PRR) allow for the installation of the necessary supports and reinforcement before the influence of the front abutment pressures, which provides a chance to improve the efficiency of moving mining machinery from the completed panel to the next working face to be extracted [].The longwall face advancing into the PRR is a critical step …

Highwall mining is an efficient, proven and durable method for mining coal from exposed horizontal seams — producing an average of 110 000 tonnes (120,000 tons) of coal per month in coal seams up to 300 m (1,000 ft) in seams dipping up to 8 degrees — recovering up to 70 percent of in-place coal. The entire mining cycle is completed by a ...
