Description
(54 ) СПОСОБ УКРЕПЛЕНИЯ МАССИВА ГОРНЫХ ПОРОД(54) METHOD OF STRENGTHENING THE MASSIF OF MOUNTAIN BREEDS
Изобретение относитс к угольной промьвиленности, а именно к способам укреплени массива горных пород при проведении и поддержании очистных и подготовительных выработок.The invention relates to coal injection, and in particular to methods of strengthening the rock mass when conducting and maintaining clearing and preparatory workings.
Известен способ укреплени грунта, включающий инжектирование в него закрепл квдего химического раствора, например, на основе полимерного св зующего и кислого катализатора (1 There is a method of strengthening the soil, which involves injecting a chemical solution into it, for example, based on a polymeric binder and an acid catalyst (1
Однако этот способ имеет недостаточную эффективность укреплени трунта. Объ сн етс это тем, что струйна жидкость скрепл ющего раствора внедр етс только в поры и трещины размером более 0,01 мм. Больша частьТрещин и пустот остаетс ненасыщенной раствором.However, this method has a lack of effectiveness in strengthening the tram. This is explained by the fact that the jet fluid of the bonding solution is inserted only into the pores and cracks larger than 0.01 mm. Most of the cracks and voids remain unsaturated with solution.
Наиболее близким к изобретению по технической сущности и достигаемому результату вл етс способ укреплени массива горных пород, включающий предварительную обработку в жущего раствора с последующим на-гнетанием его в окружающие породы через инъекторы, загерметизированные в tmypax, до полного насыщени мас1зива 2 .The closest to the invention to the technical essence and the achieved result is a method of strengthening an array of rocks, including pretreatment in a binder solution followed by pressure in the surrounding rocks through injectors sealed in tmypax until complete saturation of the mass 2.
Недостатком известного способа вл етс необходимость предварительной обработки скрепл ющего раствора и породного массива магнитным потоком , создаваемым сложной аппаратурой, а также применение хрупких дорогосто щих инъекторов из ферромагнитного материала, которые не подлежат повторному использованию/ что приводит к удорожанию работ.The disadvantage of this method is the need to pretreat the bonding solution and rock mass with magnetic flux created by complex equipment, as well as the use of fragile expensive injectors made of ferromagnetic material that cannot be reused /, which increases the cost of work.
Целью изобретени вл етс сни10 жение стоимости работ по укреплению массива горных пород.The aim of the invention is to reduce the cost of work to strengthen the rock mass.
Эта цель достигаетс тем, что согласно способу укреплени массива горных работ, включающему предвари ,15 тельную обработку в жущего раствора с последующим нагнетанием его в окружающие породы через инъекторы, загерметизированные в шпурах до полного насьвдени массива, предвари20 тельную обработку в жущего раствора производ т путем подачи в него струи сжатого воздуха, при этом нагнетание полученной аэроэмульсии прекращают при достижении уменьшени ее расхода, после чего нагнетают через This goal is achieved by the fact that, according to the method of strengthening an array of mining operations, which includes a preliminary treatment in a binder and then injecting it into surrounding rocks through injectors sealed in boreholes until the array is completely filled, the preliminary solution is produced by feeding jets of compressed air into it, while the injection of the resulting aero emulsion is stopped when the reduction of its flow rate is reached, after which it is injected through
25 инъектор необработанный раствор до полного насыщени массива.25 injector raw solution until complete saturation of the array.
На чертеже изображена принципиальна схема способа укреплени The drawing shows a schematic diagram of the method of strengthening
30 массива горных пород.30 rock mass.
