Abstract
Przedmiotem wynalazku jest ulepszenie materiału podsadzkowego, przeznaczonego do wypełniania pustych przestrzeni w podziemiach kopalń, który to materiał pochodzi z fluidalnego spalania węgla kamiennego. Istotą tego materiału jest to, że składa się on z od 10 do 90% wagowych odpadów ze spalania fluidalnego i z od 10 do 70% wagowych popiołu energetycznego, przy czym popiół ten oprócz Al2O3 i SO3, w swoim składzie zawiera od 46 do 70% wagowych SiO2 oraz od 2 do 10% wagowych CaO.The object of the invention is to improve the proppant material to be filled voids in the underground mines, which material comes from fluidized combustion hard coal. The essence of this material is that it consists of from 10 to 90% by weight of waste from fluidized combustion and from 10 to 70% by weight of energy ash, where this ash in addition to Al2O3 and SO3, it contains from 46 to 70% by weight of SiO2 and from 2 to 10% by weight CaO.
Description
Opis wynalazkuDescription of the invention
Przedmiotem wynalazku jest materiał podsadzkowy pochodzący z fluidalnego spalania węgla kamiennego, przeznaczony do wypełniania pustych przestrzeni w podziemiach kopalń, stanowiący ulepszenie materiału według patentu głównego PL (zgłoszenie nr. P.332098).The subject of the invention is a proppant derived from the fluidized combustion of hard coal, intended for filling voids in underground mines, being an improvement of the material according to the main patent PL (application no. P.332098).
Materiał podsadzkowy z fluidalnego spalania węgla kamiennego, według patentu PL 190 356 (zgłoszenie nr. P.332098) składa się z od 10 do 90% wagowych odpadów ze spalania fluidalnego zmieszanych z popiołem energetycznym w ilości od 10 do 70% wagowych i/lub produktu odsiarczania. W celu poprawienia wytrzymałości tego materiału podsadzkowego na ściskanie, do odpadów z fluidalnego spalania węgla lub mieszaniny tych odpadów z popiołem energetycznym, dodaje się odpady cementowe w ilości od 10 do 20% wagowych lub cementu w ilości od 2 do 6% wagowych.The proppant from fluidized combustion of hard coal, according to patent PL 190 356 (application No. P.332098) consists of 10 to 90% by weight of fluidized combustion waste mixed with energy ash in an amount of 10 to 70% by weight and / or of the product desulfurization. In order to improve the compressive strength of this proppant material, cement waste in an amount of 10 to 20% by weight or cement in an amount of 2 to 6% by weight is added to the waste from fluidized coal combustion or a mixture of this waste with energy ash.
Materiał ten jakkolwiek spełnia swoje zadanie ma tę niedogodność, że nie wykorzystuje wszystkie parametry techniczne materiałów odpadowych pochodzących ze spalania fluidalnego i popiołów energetycznych.Although this material fulfills its task, it has the disadvantage that it does not use all technical parameters of waste materials from fluidized combustion and energy ashes.
W praktyce niespodziewanie okazało się, że jeżeli do odpadów z fluidalnego spalania węgla kamiennego, doda się popiół energetyczny, który w swoim składzie oprócz Al2O3 i SO3 zawiera od 46 do 70% wagowych SiO2 oraz od 2 do 10% wagowych CaO, uzyskana mieszanina uzyskuje zdolność zespalania się tak, że po zarobieniu jej wodą stanowi doskonały materiał dla budownictwa, a zwłaszcza dla budownictwa drogowego do wykonywania warstw nośnych.In practice, it has surprisingly turned out that if energy ash is added to waste from fluidized combustion of hard coal, which in its composition, apart from Al 2 O3 and SO3, contains from 46 to 70% by weight of SiO2 and from 2 to 10% by weight of CaO, the obtained mixture obtains the ability to bind together so that after mixing it with water, it is an excellent material for construction, especially for road construction, for making load-bearing layers.
Materiał podsadzkowy o takim składzie komponentów nadaje się zarówno do podsadzki hydraulicznej stosowanej do wypełniania pustych przestrzeni poeksploatacyjnych, jak i do zespalania skał gruzowiska zawałowego oraz do wykonywania warstw nośnych w budownictwie drogowym, a tym samym obniżenia kosztów wymienionych wyżej prac.The proppant with such a composition of components is suitable both for hydraulic backfilling used to fill empty post-exploitation spaces, as well as for fusing rocks of cave debris and for making load-bearing layers in road construction, thus reducing the costs of the above-mentioned works.
