Abstract
The invention belongs to frame concrete pillar.Framework, cushion block that this artificial ore pillar uses are formed by reinforced concrete prefabricated, be assembled into one by leading truck, horizontal coupling bar, wedge and bolt, be used to cheat down the artificial ore pillar that artificial sill pillar and stope are made in exploitation, be convenient to adjustable height is installed, steadiness is good, enlarge the artificial ore pillar scope of application, improve the rate of extraction, reduce the ore resource loss, reduce the tunnel, reduce the cost of winning of ore.
Description
The invention belongs to frame concrete pillar.
The artificial ore pillar concrete buttress formula artificial ore pillar that adopts at present, because of being that the fritter preform is piled up neatly, so the waste raw material, poor stability can not use at the ore bed of great slope.
The objective of the invention is to use frame concrete pillar,, can improve the economic benefit of artificial ore pillar significantly in order to replace the concrete buttress.
The present invention has seven parts and forms: i.e. upper frame, underframe, leading truck, laterally coupling bar, cushion block, wedge and bolt.(above-mentioned parts are successively as accompanying drawing 1,2,3,4,5,6,7), upper frame, underframe and cushion block are all formed by the steel concrete system of giving, and are the support sections of artificial ore pillar, and leading truck adopts angle steel, and in order to guiding to be installed, making up and down, the framework direction is consistent.Laterally coupling bar adopts channel-section steel, in order to connect left and right sides framework.It is wooden that wedge adopts, in order to the wedging upper frame and make artificial ore pillar obtain contractibility.Bolt is used for leading truck is fixed on the coupling bar of bottom.The present invention is mainly used in hole exploitation down.The appearance and size of frame concrete pillar, the shape of framework, left and right sides framework distance, rod member cross dimensions, concrete grade and arrangement of reinforcement should design according to service condition and purposes.The seam floor of artificial ore pillar should be correspondingly processed according to the purposes of using.When being used as foundation, the supporting in stope polycrystalline substance tunnel should design to combine with the present invention to be carried out.
The present invention compares with prior art, and the scope of application enlarges, and can be used as the artificial sill pillar of shrinkage mining below 60 ° of ore bed inclination angle, solid ore deposit and wall type method exploitation and the artificial ore pillar of other method stope.Save raw material, be convenient to install, the time and labour saving, adjustable height, steadiness is good, improves the rate of extraction, reduces resources loss, reduces the tunnel, and economic benefit is obvious.
Shown in this accompanying drawing: 1 upper frame; 2 underframes; 3 leading trucks; 4 horizontal coupling bars; 5 cushion blocks; 6 wedges; 7 bolts.
The present invention will make in ground processing, and suitably local assembling under the hole is transported to then the place to use and adopted special-purpose utensil to install.
Claims (2)
1, a kind of concrete fritter artificial ore pillar that is used for exploitation under the solid pit, feature of the present invention is the utilization frame concrete pillar, framework, cushion block are formed by the steel concrete system of giving, and are assembled into one by leading truck, horizontal coupling bar, wedge, bolt.
2, ore pillar according to claim 1, concrete pillar framework can be rectangles, trapezoidal.
