Embodiment Construction
[0031] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0032] Figure 1-Figure 7 Shown is the preferred embodiment of the present invention for mining 4-10m steep coal seam caving hydraulic support combination.
[0033] The top-coal caving hydraulic support combination for mining 4-10m steeply inclined coal seams includes a main frame and a sub-frame, the main frame is used to support the roof and release top coal, and the sub-frame and the main frame They serve as fulcrums to realize the left and right movement of the complex.
[0034] The main frame is composed of a right part and a left part; the right part includes a right top beam 1, a right base 3, a right column 5, a left column 6 and a four-bar linkage mechanism 7; the left part includes a left top Beam 2, left base 4, rear end b...

A top coal caving hydraulic bracket combined body for exploiting a 4-10 m steeply-inclined coal seam comprises a main frame and a secondary frame, wherein the main frame is used for supporting a top plate and discharging top coal; the secondary frame and the main frame are supporting points for each other to realize left and right movement of the combined body; the main frame consists of a right part and a left part; the right part comprises a right part top beam (1), a right part pedestal (3), a right upright column (5) and a left upright column (6); the left part comprises a left part top beam (2), a left part pedestal (4) and a back end beam (8); the right upright column (5) and the left upright column (6) are used for realizing ascending and descending of the right part top beam (1) and the left part top beam (2); the back end beam (8) is connected with the back end of the left part top beam (2) and is provided with a low-position coal discharging port (801) for discharging top coal falling on the back end beam (8) from the back end of the left part of the main frame. The top coal caving hydraulic bracket combined body for exploiting a 4-10 m steeply-inclined coal seam can realize top coal caving mechanical mining of the 4-10 m steeply-inclined coal seam, effectively improves the coal mining efficiency and the production safety and greatly reduces the labor intensity of workers to a great degree.
Description
technical field [0001] The invention relates to a coal caving hydraulic support combination used for mining 4-10m steeply inclined coal seams. Background technique [0002] For steeply inclined coal seams with a thickness of less than 10m, the current common mining method is blasting mining with flexible supports. However, this mining method has poor safety, high labor intensity, and personal safety and health cannot be guaranteed. So far, there is no safe and efficient mechanized mining method for mining steeply inclined coal seams below 10m in the prior art. Contents of the invention [0003] In order to solve the technical problems of poor safety, low efficiency and high labor intensity in the mining of steeply inclined coal seams below 10m in the prior art, the present invention provides a coal caving hydraulic support combination for mining steeply inclined coal seams of 4-10m. [0004] The technical scheme that the present invention adopts is as follows: [0005] ...
