Abstract

The invention discloses a six-prop supporting split base type middle filling support. By the aid of the support, the problems that existing coal mining is low in mining rate, time-consuming and energy-consuming and potential safety hazards exist during treatment of coal gangue are solved. A side guard plate is hinged with the front end of a front top beam, a side guard jack is arranged between the side guard plate and the front top beam, a beam supporting part is arranged on a rear top beam, a telescopic jack is arranged between the beam supporting part and the rear top beam, a filling conveying machine is suspended on the beam supporting part, a four-bar linkage, two front upright props and two middle upright props are arranged between the front top beam and a front base, rear upright props are arranged between the rear top beam and a rear base, a middle filling column is arranged at the top of the rear end of the rear top beam, a swinging jack is arranged between the middle portion of the middle filling column and the top end of the rear top beam, a punning plate is arranged at the top of the middle filling column, and a punning jack is arranged under the punning plate. The support is high in adaptability to complex geological environments and capable of reducing potential safety hazards and achieving filling compaction simultaneously.

Description

technical field [0001] The invention relates to comprehensive mechanized coal mining equipment in coal mines, in particular to a six-column support split base type middle filling support. Background technique [0002] At present, my country's coal resources have proven remaining recoverable reserves of 184.2 billion tons, which can only be used for 50 years based on existing reserves and consumption levels. If the strip mining method to prevent surface subsidence is adopted, the recovery rate of coal resources is only about 40%. At the same time, the land subsidence of the national coal mining goaf due to coal mining activities has accumulated to about 1 million hectares, and the annual increase The mined-out area is about 60,000 hectares, and the cumulative accumulation of coal gangue is 4.5 billion tons, covering an area of ​​13,000 hectares. It is also increasing at a rate of about 300 million tons per year. [0003] Therefore, how to carry out safe and efficient mining o...
