Embodiment 1

[0037] A combined artificial point column suitable for mining fields, such as figure 1 , 2 As shown, it includes a supporting steel cylinder 3, a base steel plate 1 with a thickness of 12mm, a top seat steel plate 2, an expansion joint device 4 and a support frame 5, and the supporting steel cylinder 3 includes two supporting steel cylinders with a length of 0.5m and a 0.2 A supporting steel cylinder with a length of m, a supporting steel cylinder with a length of 0.1m, and a supporting steel cylinder with a length of 0.05m. The supporting steel cylinder with a length of 0.05m is connected with the supporting steel cylinder with a length of 0.05m, the supporting steel cylinder with a length of 0.2m, and the supporting steel cylinder with a length of 0.5m. An expansion joint device is installed between the steel cylinders. The expansion joint device is composed of an upper cover 4-1, an inner sleeve 4-2 and a lower cover 4-3. The inner sleeve of the expansion joint device is e...

Embodiment 2

[0049] A combined artificial point column suitable for mining fields, such as Figure 1~3 As shown, it includes a supporting steel cylinder 3, a base steel plate 1 with a thickness of 12mm, a top seat steel plate 2, an expansion joint device 4, a support frame 5, a ball head 6, and a spherical seat 7. The supporting steel cylinder 3 includes two 0.5m A supporting steel cylinder with a length of 0.2m, a supporting steel cylinder with a length of 0.1m, a supporting steel cylinder with a length of 0.05m, and a supporting steel cylinder with a length of 0.5m connected above the base plate , a ball head with a diameter of 20cm is connected under the steel plate of the top seat. The ball head is a sphere cut 5cm along its diameter direction. The ball head is placed in the ball head seat. The bottom of the 0.05m-length support steel cylinder is connected with the 0.1m-length support steel cylinder, the 0.2m-length support steel cylinder, and the 0.5m-length support steel cylinder in ...

Abstract

The invention relates to a combined type artificial pillar suitable for a stope. The artificial pillar comprises a plurality of supporting steel cylinders of different specifications, a top steel plate, a bottom steel plate, expansion steel cylinders and a supporting frame. Each supporting steel cylinder is formed by welding steel plates to the two ends of a steel pipe. Each expansion steel cylinder is composed of an upper cover, a lower cover and an inner cylinder body. The lower portion of the top steel plate and the upper portion of the bottom steel plate are connected with the supporting steel cylinders which are sequentially connected with one another. The expansion steel cylinders are installed between the supporting steel cylinders and located at the lower middle portion of the supporting pillar. The lengths of the supporting steel cylinders above the expansion steel cylinders are sequentially decreased from bottom to top. The top steel plate, the bottom steel plate and the supporting steel cylinders are fixedly connected through screws, the supporting steel cylinders are fixedly connected through screws, and the supporting steel cylinders and the expansion steel cylinders are fixedly connected through screws. The artificial pillar has the advantages that the height of the supporting pillar can be adjusted according to the cylinders of different lengths, the higher the position is, the smaller the length of the cylinders is, and construction is easy; cost is low, borehole waste steel rails and waste pipelines can be sufficiently used as supporting stand columns, and cost is saved to the maximum extent.

Description

technical field [0001] The invention relates to a support point column, in particular to a combined artificial point column used in a mining field and an installation method thereof, belonging to the technical field of mining. Background technique [0002] The Shangzhuang mining area in Zhaoyuan City is located in the northeast section of the Wangershan ore-bearing alteration zone. Its ore body is an altered rock type gold deposit. The ore body is strictly controlled by fault structures and is located on the hanging wall of the main fault surface. After decades of mining, its shallow resources have been exhausted, and the mine has gradually entered the deep mining stage. The average dip angle of the ore body in Shangzhuang mining area is 20-25°, and the average horizontal thickness is 20m-30m, which belongs to a typical gently inclined medium-thick ore body. At present, the upward horizontal layered tailings filling mining method is adopted for mining, the ore is dropped th...
