The invention relates to the mining industry and can be used in the development of cool - and nalandabodhi very thin mineral deposits.
There is a method of developing vein deposits system with magazynowania ore (see, for example, "Development of mineral deposits of Kazakhstan". Volume 1. "Development of mineral deposits". M, Gosgortechnadzor, 1963, page 317, RES. System magazynowania ore), in which the blocks are prepared by drilling haulage drift, from which are passed niches, Gucci and funnel or under construction along the entire length of the block loading shelves. Practicing the camera starts with education sweeps and layered grooves, while workers are on tamakaimoana the ore body. To access the store are rising and checked, passed in mezhdurebernyh the pillars. As the conditions are partially ore generation through the bottom. After blasting chamber stockpiles and ore from cameras obrushayutsya Mezhdunarodnye pillars and PetroChina. The disadvantages of this method are: 1) a huge amount of preparatory-threaded work, 2) large losses and dilution of ore, especially when pulling mezhdurebernyh pillars and crown pillars, 3) low intensity excavating and cleaning work, 4) the volume of excavated when the rotating drum and the cameras what's reserves breed several times more volume of core mass, 5) the danger of finding people in a mining space. Store width 1-1,2 m bounces the rock mass layers height of 2-2,5 meters While workers are clearing space on tamakaimoana ore, exposed to the danger of falling of the wall rock and ore, as well as tamakaimoana ore. When developing ore veins ranging from 0.2 to 0.5 m volumes extracted in this way the ore mass several times greater volumes of core mass, and the proportion of diluting rocks ranges from 0.5 to 0.6 to 0.8-0,83. Therefore, the proportion of ore this ore mass is only from 0.17 to 0.45. The main costs are for the extraction and processing of rock. In addition, a large dilution leads to a decrease in extraction of metals during enrichment on 15-16%, and the content in concentrates 5-8%.
There is also known a method of developing thin lived sublevel drifts adopted for the prototype (see, for example, Agoshkov M.I., S. Borisov, boyar, VA "Development of ore and placer deposits". M, Gosgortechnadzor, 1962, s, RES. Excavation of the sublevel advanced faces), which was used during the development of the sinews of power from 8-10 cm up to 20-30 cm In this method, the floor height of 30-40 m was divided into blocks of length 50 m Training unit was made by drilling haulage drifts on vein at the level of the main horizon. From drift stope prepared, as usual, ser is her duchek and funnels, education sweeps, and for the conditions of the stocks of the passed through the center of the camera on the ore to bomb it rocks hanging of the side of the rebels were several sublevel drifts section 2×0.8 m2every 6,5-7,5 m Of drifts drilled up and down the bore holes for blasting stock camera. Repulsed ore mass produced through the workings of the bottom. The disadvantages of this method are that it is necessary to perform a huge amount of preparatory-rifled works almost on the breed, especially for sinking workings of the bottom, which is very large ore ore with all the ensuing consequences for the results of extraction and enrichment. Workers have to be in the drifts are very small cross section and move them to itself under threat of collapse from the outdoor treatment space above the broken podathey. Limited section sublevel drifts do not allow the use of high-performance equipment, causing low productivity and the intensity of work on the preparation of inventories, and the location of the rising and sublevel drifts of the open clearing space creates a hazard to employees.
The invention is aimed at reducing time-consuming preparatory-threaded operations, reduce losses and dilution of minerals, improving the intensity and safety of mining operations, due to the fact that the development of low-power fields includes split floor section extended upwards hexagonal shape, holding haulage drifts and rising, characterized in that the floor is divided into sections (camera) without leaving mezhdurebernyh pillars and is prepared by drilling field haulage drift, drift under each section are races, which are useful to fossil are rising, intended for drilling of them horizontal or inclined drilling and blasting inventory sections (chambers), in this issue of smitten rock mass through the ends of the races, and after the release of the rock mass from all sections cameras) has been coming down the ceilings and available also through the ends of the races.
The invention is represented in the drawings, in which figure 1 is a projection on a vertical plane method development figure 2 is a vertical section along the line I-I.
How to develop a thin and very thin cool - and nalandabodhi mineral deposits is as follows. Reserves adjacent floors are divided into sections extended upwards hexagonal shapes offset by half the width of the section on each of the adjacent floor. Angles α the lower parts of the chamber should be more angles of repose smitten rock. Preparation of each floor Khujand is realized by sinking a field haulage drift (1) in the supine side, which under each section are short races (2). Race prepared floor pass (if necessary with sticking breed) rising (3) the full height of the section to leave on an upper floor ceiling pillar zigzag form (4). Between sections (chambers) pillars do not leave. The breaking of the main stocks (sections) of the camera is carried out in revolt (3) by drilling horizontal or directional wells (5) and blasting them one at a time from the bottom up. The lower part of the sections discourage any system with magazynowania or blowing fans wells (6), probatively of arrival (2) of the main horizon (1). From the haulage drift of the upper horizon (floor) are the races (7) to itself to ensure safe access to the site of drilling and blasting holes after blasting stocks lower part of the section (camera). Smitten the rock mass is produced through the end of check-in (2) main haulage horizon drift (1). After the release of ore from all sections (chambers) we have one large camera without mezhdurebernyh pillars. After that race above the floor (7) drilled and interfloor has been coming down the pillar-ceilings (4). This method of development is significantly reduced amounts of tunneling works, including breed, increases the intensity of the preparation and of istih works losses are reduced (especially by eliminating mezhdurebernyh pillars) and ore minerals by reducing the mining power and volume working driving. The result dramatically increases the production capacity of the mine and concentrator, and reduced capital and operating costs of mining and milling in the calculation of the final products. In addition, increases safety, because the workers are always securely fastened in openings (rise and races).
How to develop a thin and very thin cool - and nalandabodhi fields, including the division of the floor section extended upwards hexagonal shape, holding haulage drifts and rising, characterized in that the floor is divided into sections and prepare a sinking field haulage drift, drift under each section are races, which are useful to fossil are rising, intended for drilling of them horizontal or inclined drilling and blasting inventory sections, with the release of the smitten rock mass are carried out through the ends of the races, and after the release of the rock mass from all sections will obresult ceilings and release through the ends of the races.
