Abstract

The invention discloses a thin coal seam separated mining, separated conveying, filling and producing hydraulic support which comprises a base. A top beam is arranged on the upper side of the base. Aplurality of telescopic stand columns are arranged between the base and the top beam. A supporting plate capable of extending forwards is arranged on the lower side of the front end of the top beam. Afilling scraper conveyer is arranged on the rear side of the top beam. By means of the thin coal seam separated mining, separated conveying, filling and producing hydraulic support, the purpose of separating mined coal gangue in a thin coal seam is realized, and meanwhile the problem that a support cannot support a rock layer above a coal layer through a falling frame during separated mining andseparated conveying is solved.

Description

technical field [0001] The invention belongs to the technical field of coal mine filling mining hydraulic supports, in particular to a thin coal seam separate mining and transport filling mining hydraulic support. Background technique [0002] Thin coal seam refers to the thickness of coal seam below 1.3 meters. my country's thin coal seam coal reserves are relatively abundant. According to surveys, my country's thin coal seam reserves are about 67 billion tons. With the intensification of mining efforts in medium and thick coal seams, coal resources are becoming less and less. Although the mining prospects of thin coal seams are very broad, the degree of development and utilization is not high. The main reason is that the mining technology of thin coal seams is compared with medium and thick coal seams. Thick coal seams have higher requirements and the environment is more complex. [0003] Due to the thin coal seam, the mining space is too narrow, it is difficult to erect ...
