Description
Изобретение относитс к горному д;елу и может быть использовано при дозакладке карстовых и техногенных полостей карбонатными материалами при их размыве или усадке, при сооружении на карьерах противофильтрационных завес, ограждающих от притока грунтовых вод,при заполнении полостей , образующихс в результате подземной выплавки серы, а также при строительстве дамб, гидросооружений и других объектов на закарстрванной. территории.The invention relates to the mountainous spruce and can be used in dozakladka karst and man-made cavities carbonate materials during their erosion or shrinkage, the construction of antifiltration curtains on the quarries, protecting from groundwater inflow, when filling cavities resulting from underground smelting also in the construction of dams, hydraulic structures and other objects at the site. territory.
Известен способ.дозакладки пустот закладочной смесью с газообразующей добавкой (алюминиевой пудрой). Одновременно -в трубопровод в качестве замедлител реакции ввод т порс икообразную борную кислоту дл того, чтобы газовыделение происходило после окончани укладки закладочной смеси с газообразующей добавкой в дозакладываемой полости, иначе расширение произойдет в трубопроводе, что . недопустимо по услони м транспортировани 1 J.The known method. Dozakladki void filling mixture with a gas-forming additive (aluminum powder). At the same time, a porsy and boracous boric acid are introduced into the pipeline as a moderator of the reaction in order for the gassing to occur after the termination of the filling of the filling mixture with the gas-forming additive in the cavity to be laid, otherwise the expansion will occur in the pipeline. unacceptable for transportation conditions 1 J.
Недостатками этого способа Дозакладки пустот вл ютс использование дорогосто щих заклпдочных материалов , а также больуьл коэффициент фильтрации и недостаточное расширение закладочного материала.The disadvantages of this method of backfilling of voids are the use of expensive stopping materials, as well as a large filtration coefficient and insufficient expansion of the filling material.
Известен также.вспенивающийс легкий заполнитель в виде гранул, содержащих пенополистирол смешанный с керамическим порошком, вспучивание которого происходит в результате обжига гранул 2 .Also known is a foaming, lightweight aggregate in the form of granules containing expanded polystyrene mixed with ceramic powder, which swelling occurs as a result of burning of the granules 2.
Недостатками использовани данного заполнител вл ютс невозможность осуществлени операции обжига под землей в услови х обводненных карстовых полостей, относительна дороговизна керамического материала, а также водопроводимость -закладочного материала за счет его растрескивани и наличи межпорового пространства.The disadvantages of using this filler are the impossibility of carrying out the operation of firing underground in conditions of watered karst cavities, the relative high cost of ceramic material, as well as water conductivity of the filling material due to its cracking and the presence of interpore space.
Цель изобретени - обеспечение полноты дозакладки, кольматаци закладочного материала и равномерное распределение кольматирующего реагента по всему закладочному материалу, а также распределение реагента по возможна большей части массива.The purpose of the invention is to ensure the completeness of backfill, clogging of the filling material and uniform distribution of clogging reagent throughout the filling material, as well as the distribution of the reagent over most of the array.
