Description
Изобретение относитс к области горного дела и касаетс способа разрушени угл при гидродобыче.The invention relates to the field of mining and relates to a method for the destruction of coal during hydro-mining.
Целью изобретени вл етс улучшение технологии добычи угл из мощных крутых Пластов при гидромеханизации и повышение безопасности труда.The aim of the invention is to improve the technology of coal mining from powerful steep seams during hydromechanization and increase in occupational safety.
Дл этого предложено рыхление угл производить самообрушепием угольного массива на компенсационный объем под действием сил гравитации. При этом компенсационный объем образовываетс путем вымывани угл тонкими стру ми воды.To this end, it has been proposed to loosen the coal by producing self-destructive coal in the massif to the compensation volume under the action of gravitational forces. In this case, the compensation volume is formed by leaching the coal with thin streams of water.
На фиг. I показан план отработки участка; На фиг. 2-разрез по Л-А на фиг. 1; ма фиг. 3 - установка дл рыхлени угл .FIG. I shows the plot development plan; FIG. 2 is a section along the line in FIG. one; ma fig. 3 - installation for loosening coal.
Выемочный участок вскрывают квершлагаМи на откаточном / и вентил ционном 2 горизонтах . Этаж высотой 80-100 м дел т по падению проведением штреков 3 на подэтажи 4. Из подэтажных штреков 3 бур т скважины 5.The extraction area is opened with openings on the haulage / and vent 2 horizons. The floor height of 80-100 m is divided by the fall of making drifts 3 to the subfloor 4. From the sublevel drifts 3 are drilled wells 5.
Из скважин дл создани компенсационного объема стру ми воды из насадок 6 частично вынимаетс уголь. В результате образуетс полость 7. Штанги 8 укорачивают. Снова отбивают уголь и образуетс нова полость 9 и т. д.Coal is partially removed from the wells to create a volume of compensation with jets of water from nozzles 6. As a result, a cavity 7 is formed. The rods 8 are shortened. The coal is fought off again and a new cavity 9 is formed, etc.
Образующиес полости вл ютс компенсационным объемом, позвол ющим при определенной его величине (25-30%) и наличии горного давлени обрушить оставшуюс часть угл .The cavities formed are a compensation volume that, with a certain value of it (25-30%) and the presence of rock pressure, bring down the rest of the coal.
Предмет изобретени Subject invention
Способ рыхлени угл нри разработке мощных крутых пластов, отличающийс те.м, что рыхление угл производитс самообрушением угольиого массива на компенсационный объем под действием сил гравитации, при этом компенсационный объем образовываетс путем вымывани угл тонкими стру ми воды высокого давлени .The method of loosening coal by developing powerful steep seams, characterized by the fact that coal loosening is performed by self-crushing of the coal mass on the compensation volume under the action of gravity forces, while the compensation volume is formed by washing the coal with thin jets of high pressure water.
