Mine working lining method

FIELD: mining.

SUBSTANCE: rock lining method involves erection of n-coal liner in filling mass from equal n-elements along helical spiral, installation of hollow guide template on bearing set prior to erection of filling mass, which repeats contours and clear sizes of development and the height of which is more than filling increment. At that, lining elements are laid on outer surface of template; after that filling mass is erected around liner; then template is lifted through one filling increment; sequence of operations is repeated till the liner erection is completed.

EFFECT: maintaining straightness of development liner during erection.

The invention relates to the field of mining and can be used for fastening the vertical and inclined mine workings, erected in filling the array.

There is a method of securing mining circular cross-section (A.S. No. 1696714 A1, MKI 21D 11/00, publ. 07.12.91, bull. No. 45), which includes the construction of a closed n-carbon lining of the short elements.

The disadvantages of this method are the inability of the joint force interaction of adjacent frames and mnogovershinnoe technology of erection of the lining.

There is also known a method of securing mining circular cross-section (A.S. No. 1751344 A1, MKI 21D 11/14, publ. 30.07.92. Bull. No. 28), which includes the construction of spiral lining of equal curvilinear segments (elements)connected end-to-end, installation between adjacent elements of the elastic strips to ensure compliance lining.

The disadvantages of this method are: the complexity of the design of the lining, the impossibility of its production of the most frequently used mounting materials, such as wood, wood thrown rocks in the production of inter-turn space, inappropriate use in mines, constructed in filling the array.

There is a method of securing mining, erected in filling array (Patent RF №2348810 C1 IPC 21D 5/00, publ. 10.03.2009), selected as the e prototype which includes the construction of filling in the array of n-carbon lining of n equal elements along a helical spiral.

The disadvantage of this method is the care of the output from the longitudinal axis due to the displacement of adjacent turns of the supports relative to each other at the time of construction of the backfill array.

The objective of the invention is maintaining the straightness generation during the construction of the liner.

This task is achieved in that in the method of securing mining, which includes the construction of filling in the array of n-carbon lining of n equal elements along a helical spiral, the installation before erecting the backfill array on the abutment crown hollow guide template, which follows the contours and dimensions of the working in the light, the height of which more step bookmarks, according to the invention the lining elements are placed with the outer surface of the template, and then around the lining erect filling the array, the template then raise on step bookmarks, the procedure is repeated until the completion of the construction of the lining.

The invention is illustrated by drawings, where:

figure 1 shows enshrined in roof 1 transport drift anchor support 2 support crown 3 has mounted on it a guiding template 4;

figure 2 shows the sectional construction of the n-polygonal spiral lining around 5 guide template on Velich is well, equal step bookmarks - h3;

figure 3 shows the connection elements lining 5 clips 6;

figure 4 shows the construction of the backfill array 6 built around support in an amount equal to the step bookmarks - h3;

figure 5 shows a section along the longitudinal axis erected in filling array shield production with movable guiding template for an amount equal to the step bookmarks h3.

The method of securing mining is as follows.

In roof 1 above the transport roadway fix anchor support 2 support crown 3, on which is mounted a hollow drill template 4. Around the template spiral spiral stack elements 5 n-carbon lining of equal elements by an amount equal step bookmarks - h3. Adjacent lining elements are fastened to each other by metal brackets 6. Then built around shield production erect backfill array 7 by an amount equal step bookmarks. Then the guide template to raise an amount equal to the step bookmarks - h3. At the time of construction of the backfill array pattern is hard pillar lining and prevents displacement of adjacent coils relative to each other. Then the cycle of operations is repeated as podvigina front of wastewater treatment works.

An example of a specific application of the method. In the crown pillars is 1 above the transport drift fixed abutment crown 3 using anchor lining 2 (the number and length of anchors depends on the physico-mechanical properties of the wall rock). On the abutment crown set hollow drill template 4, which follows the contours and dimensions of the cross-section generation in the world, at a height of 1.8-2.0 m (1,8-2,0 m - width removable strip, equal step bookmarks). Start around the template spiral spiral lay the lining elements 5. If you make items lining timber section 200 x 200 mm, the number of turns in the shield depending on the step bookmarks will be equal to 9, 10. To provide communication between adjacent elements in the circuit fasten their metal clips or pins 6 or pre-lining elements strung on a flexible basis. Built around thus shield erect filling the array 7. By means of a hoist or other lifting device guide template is lifted up. The bottom of the template stays in erected lining. The cycle of operations by the erection of the lining is repeated until the completion of the construction of the lining.

The proposed method of fastening vertical and inclined mine workings, erected in filling the array has the following advantage: maintaining the straightness generation during the construction of the liner.

The method of securing mining, which includes the construction of filling in the array of n-carbon lining of n equal elements along a helical spiral, the installation before erecting the backfill array op is RNA the crown of the hollow guide template, repeating the contours and dimensions of the working in the light, the height of which more step bookmarks, characterized in that the lining elements are placed with the outer surface of the template, and then around the lining erect filling the array, the template then raise on step bookmarks, the procedure is repeated until the completion of the construction of the lining.

SUBSTANCE: present invention pertains to mining and can be used for supporting vertical and inclined mines, built on filling mass. The invention seeks to simplify the design of support for vertical and inclined mines, built on filling mass. This objective can be reached by that, the method involves building on filling mass, n-cornered support from equal-sized n-elements on a helical spiral. According to the invention, before building the filling mass, a hollow former is fitted, repeating the contours and dimensions of the rough section of the goaf, the height of which is greater than the stowing increment. Then later, inside the former, support members are fitted at a value equal to the stowing increment, fastening them to each other using clamps, dowels etc. The former is then raised to a height, equal to the stowing increment. The filling mass is built around the support. This sequence of operations is repeated until the support is built along the whole goaf.

SUBSTANCE: present invention relates to the mining industry and may be used for protecting mine workings and intersections thereof against damage during underground mining of fields. The protection method involves forming an unloading area by drilling deformation wells around the mine working being protected. Part of the wells outside the protected area are filled with backfill material. The length of the unfilled part is calculated from the expression LA=LW+0.5B1,+0.5B2, where: LW is the length of the mine working protected (m); B1 and B2 are distances from the deformation wells to the mine working protected, correspondingly, the least and the most, m. The unloading area is formed by drilling deformation wells from an active mine working so as to provide mutual intersection of the wells.

EFFECT: increased protection efficiency and decreased costs for field development due to redistribution of stresses in rock mass.
