Abstract

The invention discloses a high fully mechanized filling, mining and screening hydraulic support, which comprises a top beam, a front canopy arranged in front of the top beam, upright posts for supporting the top beam and a rear top beam arranged at the tail of the top beam, wherein a filling material conveyer is arranged below the rear top beam; the filling material conveyer is suspended below the rear top beam; a high pushing and pressing device is connected with the rear top beam; a low pushing and pressing device is arranged on a base below the rear top beam; a coal discharge hole is formed between the front beam and the rear top beam; a telescopic jack is connected with the coal discharge hole; a screening device is arranged at the coal discharge hole; the screening device is connected with the front beam and the rear top beam by wedge-shaped chutes; the screening device is provided with a telescopic lateral gangue discharge passage; a scraper conveyer is arranged below the screening device; and a scraper trough is fixed on the base. The hydraulic support can be used for supporting a fully mechanized working face, can realize underground coal discharge, coal dressing, gangue discharge and complete filling of a goaf, is simple in process, and is widely used.

Description

technical field [0001] The invention relates to a high-level fully mechanized caving and filling mining screening hydraulic support, which is especially suitable for the simultaneous support, coal mining, coal caving, coal preparation and filling of comprehensive mechanized top coal caving and filling coal mining working faces in mines. technical background [0002] During the mining process of coal mines, it is often faced with a series of problems such as environmental pollution caused by accumulation of waste rock on the ground, ground coal preparation plants occupy a large amount of land area, and "three-down" coal pressure. Utilizing underground gangue filling replacement coal mining and underground coal preparation technology can not only realize the high recovery rate mining of deep coal resources on the basis of ensuring the safety of ground buildings, but also solve the problems caused by gangue stacking on the ground and the occupation of ground coal preparation pla...
