Abstract
The invention provides a pillar mining method. According to the structure of supporting columns, the supporting columns are prefabricated by reinforced concrete, the cross section of each supporting column is in the shape of a square column, each supporting column is divided into an upper section and a lower section, a supporting column top is arranged on the upper portion of each seam, a round hole is formed between the seams, and a threaded jacking rod is arranged in the round hole. The pillar mining method comprises the following steps of abutting the prefabricated supporting columns to a pillar; excavating the pillar; and remaining or abandoning the supporting columns after the pillar is excavated. The pillar is clamped by the two supporting columns and is excavated, the supporting columns are withdrawn after mining and are abandoned in a mine or taken out from the mine, precious mineral resources can be utilized sufficiently, and the social benefit is improved. The pillar mining method is suitable for mining pillars.
Description
Technical field
The present invention is to provide the method for mining machinery field for digging up mine, specifically a kind of pillar exploitation method.
Background technology
At present, in mining process, in order to increase strength of roof, prevent landslide, usually pre-pillar, ore pillar is generally ore shoot, more owing to building ore pillar, so cause a large amount of ore to waste, some pillar strength is low, so usually cause ore pillar to collapse, thus loses the supporting role of ore pillar.After mining completes, a large amount of ore pillar that stays is stayed in hole, ore deposit, causes mineral resources to waste, and thus how to exploit ore pillar, accomplishes that the utilization of resources is the problem needing to solve.
Have a kind of method at present, denomination of invention is frame concrete pillar, and the patent No. is CN85102494A, and clip Text is that this invention belongs to frame concrete pillar.This people's industrial and mineral
The framework that post uses, cushion block are formed by reinforced concrete prefabricated, one is assembled into coupling bar, wedge and bolt by leading truck, branch, doing the artificial ore pillar of artificial sill pillar and stope for cheating lower exploitation, being convenient to install, adjustable height, steadiness is good, expand the artificial ore pillar scope of application, improve the rate of extraction, reduce ore resource loss, reduce tunnel, reduce the cost of winning of ore.
The artificial ore pillar structure that this method uses is: form artificial ore pillar by two-sided concrete column, pass through wedge plate supporting between concrete upper piles and lower piles.There is shortcoming is that wedge is subject to size restrictions and angle limits, when angle is large, can not squeeze into, when angle hour easily relaxes again, not produce supporting role, therefore considers from structure and operating principle angle, can not reach imagination effect, that is inapplicable.
Above patent as the artificial ore pillar supported, can only not have actual application value for natural pillar exploitation.
Summary of the invention
In order to overcome the shortcoming of prior art, the present invention proposes a kind of pillar exploitation method.The method, by two support column common support ore bodies, exploits the ore pillar be placed between two support columns, solves the technical problem of pillar exploitation.
The scheme that technical solution problem of the present invention adopts is:
Support column arrangement: by reinforced concrete prefabricated one-tenth support column, described support column cross section is square-column-shaped, and support column is divided into two sections, on seam top, support capital is housed, between seam, is provided with circular hole, at circular hole built with screw thread lifting pin.
Pillar exploitation method: by two prefabricated support columns near pillar, excavates pillar, selects retain support column or abandon support column after having excavated pillar.
Good effect, the present invention utilizes two support column clamping pillars, and exploitation pillar, withdraws from support column after exploitation, discards in ore body or takes out, therefore, it is possible to make full use of valuable mineral resources, increases social benefit.Be suitable for applying as pillar exploitation method.
Accompanying drawing explanation
Fig. 1 is pillar mining distribution schematic diagram of the present invention
Fig. 2 is support column arrangement schematic diagram of the present invention
In figure, 1. pillar, 2. support column, 3. support capital, 3.1. seam, 4. screw thread lifting pin.
Detailed description of the invention
According to the figure,
Support column arrangement: by reinforced concrete prefabricated one-tenth support column 2, described support column cross section is square-column-shaped, and support column is divided into two sections, is equipped with and supports capital 3, be provided with circular hole, at circular hole built with screw thread lifting pin 4 between seam on seam 3.1 top.
Pillar exploitation method: by two prefabricated support columns near the pillar 1 in hole, ore deposit, excavates pillar, selects retain support column or abandon support column after having excavated pillar.
Advantage of the present invention:
1, make full use of the mineral resources of pillar, improve ore extraction rate.
2, support column makes support capital close contact ore deposit push up by the action of screw thread lifting pin, makes firm supporting, is conducive to construction, analyzes and in practical effect, be superior to the artificial ore pillar adopting wedge to carry out jacking from know-why.
3, support column can be reused, saving resource.
Claims (1)
1. a pillar exploitation method, is characterized in that: by reinforced concrete prefabricated one-tenth support column, and described support column cross section is square-column-shaped, support column is divided into two sections, on seam top, support capital is housed, between seam, is provided with circular hole, at circular hole built with screw thread lifting pin;
By two prefabricated support columns near the pillar in hole, ore deposit, excavate pillar, select after having excavated pillar retain support column or abandon support column.
