Supporting device for coal mine underground shaft bottom inclined mining

Abstract

The invention discloses a supporting device for coal mine underground shaft bottom inclined mining, and belongs to the field of coal mining. The supporting device for coal mine underground shaft bottom inclined mining comprises a mounting frame, a scraper mechanism, a baffle mechanism, a box body and a locking mechanism. The scraper mechanism is arranged above a top plate, the baffle mechanism is arranged on the open side of the top plate, and the box body capable of ascending and descending is arranged at the lower end of the baffle mechanism, so that broken stone soil is unloaded in the box body, and potential safety hazards caused by too much broken stone soil accumulated on the top plate are avoided; the locking mechanism is arranged on the mounting frame, so that the situation that when the box body does not reach the highest point, a baffle is far away from a second limiting plate, the height difference of unloading of the broken stone soil is large, and the broken stone soil cannot completely fall into the box body is avoided; and a first auger and a second auger which are opposite in rotating direction are arranged in the scraper mechanism, so that soil attached to the upper end of the top plate is loosened.

Description

technical field [0001] The disclosure belongs to the field of coal mine mining, and in particular relates to a support device for shaft bottom syncopation in a coal mine. Background technique [0002] In coal mine production, the underground mining method is the most important method. Therefore, the study of underground mining technology has very important practical significance. The application of underground mining technology must be adapted to the coal mine geology and coal seam distribution, and the mining plan must be formulated in advance. Determine the application of equipment and support methods. In open-pit mining, direct mining is generally used, but in underground mining, due to the constraints of the environment and equipment, the anticline method is usually used; with the continuous development of mining technology, syncline mining The method has gradually been widely used, etc.; [0003] In mines, it is usually necessary to build a support device. The support ...
