The combined support column 2 is formed by splicing a plurality of hollow support columns 21, wherein the upper end of the hollow support column 21 at the topmost end of the combined support column 2 is fixedly connected with a support plate 1, the lower end of the combined support column is fixedly connected with a connecting plate 22, the upper end and the lower end of each hollow support column 21 are fixedly connected with connecting plates 22, and every two hollow support columns 21 are connected through a connecting plate 22 bolt.
The connecting plate 22 is provided with a plurality of bolt holes 23.
The supporting plate 1, the base 5 and the connecting plate 22 are all steel plates.
The hydraulic jack 4 is a finished product hydraulic jack.
The hollow support column 21 is a seamless steel pipe with the height of 100cm, 50cm, 30cm, 20cm or 10cm, and needs to be combined and spliced according to the height of a stope in use.
The utility model has the advantages that:
in the exploitation of the gently inclined thin ore body, in order to ensure the stability of the stope, the top plate needs to be supported, and through the use of the artificial prop, the problems that the reserved natural ore pillars cause ore loss and the higher ore body hydraulic prop cannot be used can be effectively solved, and the supporting efficiency of the stope is improved. The device simple structure, the preparation is convenient, and the material source is extensive, and through the use of this device, convenient operation, work efficiency are high, can greatly reduced the loss rate in stope, and this pillar can be retrieved reuse again, has practiced thrift the cost of strutting for the exploitation in mine.
