Description
Przedmiotem wynalazku jest sposób oznaczania rozchodzenia sie wody i wodnych roztworów zwlaszcza w caliznie weglowej.W celu zmniejszenia naturalnej sklonnosci wegla do tapan stosuje sie tzw. aktywne metody ich zwalczania miedzy innymi poprzez nawilzanie pod wysokim cisnieniem pokladów weglowych. Dla zwiekszenia efektywnos¬ ci nawilzania pokladów weglowych stosuje sie niekiedy dodatki z alfenolu lub nekalu. Srodki te dodane do wody znacznie poprawiaja skutecznosc nawilzania. Ze wzgledu jednak na niejednorodnosc struktury wegla nie nastepuje nawilzanie penetracyjne, poniewaz woda przeciskana bywa miejscami pomniejszonej spoistosci.W przypadkach tych nie ma mozliwosci stwierdzenia w jakim stopniu dany rejon jest nawilzony, a w praktyce jest rzecza bardzo wazna by kontrolowac prawidlowosci i skutecznosci nawilzania. i Znany jest sposób kontroli nawilzania prowadzony przy pomocy regularnego pomiaru wilgotnosci w próbach weglowych pobranych z nawilzajacej calizny weglowej. Inny ze znanych sposobów polega na obserwacjach wykraplania sie wody na ociosie weglowym w trakcie nawilzania, oraz podczas pracy maszyn urabiajacych. Sposoby te sa pracochlonne, niedokladne i nie daja gwarancji prawidlowosci i skutecznosci nawilzania. < Istota rozwiazania wedlug wynalazku jest zastosowanie do zwilzenia pokladów wegla znaczników emanujacych w promieniach ultrafioletowych zwanych helioforami, które wprowadza sie do wody lub roztwo¬ rów wodnych. Przygotowane medium pod wysokim cisnieniem i/lub wykorzystujac cisnienie kapilarne wtlacza sie w calizne weglowa, a nastepnie oznacza sie penetracje przez naswietlanie wiazka promieni ultrafioletowych odkrytej plaszczyzny weglowej.Zaleta rozwiazania wedlug wynalazku jest bardzo dokladne stwierdzenie rozchodzenia sie mediów zwilzajacych, majace zasadnicze znaczenie w praktyce górniczej. Dzieki tej metodzie istnieje mozliwosc ograniczenia tapan.Przyklad. 1000 litrów wody miesza sie z 1 litrem helioforu, nastepnie roztwór wtlacza sie w calizne weglowa pod cisnieniem 300 atm. Wykonuje sie przekrój calizny weglowej, która naswietla sie wiazka promieni2 97 639 ultrafioletowych. W miejscach przeplywu medium zwilzajacego powstaje intensywne swiecenie. Sposób ten moze byc równiez stosowany na przyklad przy okreslaniu skutecznosci urzadzen odpylajacych stosujacych szczególnie odpylanie mokre, okreslaniu ruchu wód kopalnianych, gruntowych, skutecznosci dzialania oczyszczalni scieko¬ wych, przy stosowaniu flotacji, kontroli opylania wyrobisk górniczych oraz okreslaniu rozkladu spoiwa w budownictwie. PLThe subject of the invention is a method of determining the distribution of water and aqueous solutions, especially in carbonaceous bodies. In order to reduce the natural tendency of carbon to tapan, the so-called active methods of combating them, inter alia, by moistening the coal seams under high pressure. In order to increase the effectiveness of hydration of coal seams, additives made of alfenol or necal are sometimes used. When added to the water, these agents significantly improve the hydration efficiency. However, due to the heterogeneity of the carbon structure, there is no penetration wetting, because the water is squeezed out of places of reduced cohesiveness. In these cases, it is not possible to determine to what extent a given region is humidified, and in practice it is very important to control the correctness and effectiveness of hydration. i It is known to control the moisture content by means of regular humidity measurements in coal samples taken from the moistening coal pool. Another known method consists in observing the condensation of water on the coal wall during moistening and during the operation of mining machines. These methods are laborious, inaccurate and do not guarantee the correctness and effectiveness of the hydration. The essence of the solution according to the invention is the use of markers emitting ultraviolet rays, known as heliophores, which are introduced into water or aqueous solutions, to wet the carbon deposits. The prepared medium under high pressure and / or using capillary pressure is forced into the carbon body, and then the penetration by irradiating a beam of ultraviolet rays of the exposed carbon plane is marked. The advantage of the solution according to the invention is a very accurate determination of the dispersion of wetting media, essential in mining practice . With this method it is possible to limit tapan. Example. 1000 liters of water is mixed with 1 liter of heliophore, then the solution is forced into the carbon under a pressure of 300 atm. A cross-section of a carbon body is made which is illuminated by a beam of ultraviolet rays. In places where the wetting medium flows, intense shine is created. This method can also be used, for example, when determining the efficiency of dust removal devices, especially wet dust removal, determining the movement of mine and ground water, the effectiveness of wastewater treatment plants, when using flotation, dusting control of mining excavations and determining the distribution of binder in construction.
