Description
Przedmiotem wynalazku jest sposób preparacji wegla lub górotworu inhibitorami.The subject of the invention is a method of coal or rock mass preparation with inhibitors.
Znane dotychczas sposoby zmiany wlasnosci mechanicznych calizny weglowej lub wegla polegaja na wtlaczaniu pod cisnieniem wody lub roztworów wodnych do calizny weglowej.The hitherto known methods of changing the mechanical properties of coal or carbon consist of injection of water or aqueous solutions into a coal tank under pressure.
Znany sposób z polskiego opisu patentowego nr 71741 polega na wtlaczaniu pod cisnieniem od 100—300 atm wodnego roztworu zawierajacego od 0,05 do 5% wagowych soli sodowej kwasu butylonaftaleno-sulfono- wego, lub tez zawierajacego od 0,05-5% wagowych produktu addycji tlenku etylenu i nonylofenolu.The known method from the Polish patent specification No. 71741 consists in injection under a pressure of 100-300 atm of an aqueous solution containing from 0.05 to 5% by weight of sodium salt of butylnaphthalene-sulfonate % or containing from 0.05-5% by weight of the addition product of ethylene oxide and nonylphenol.
Celem wynalazku jest zapobieganie powstawania reakcji utleniajaco redukcyjnych w weglu powodujacych poprzez wzrost temperatury pozary dolowe oraz pozary zwalów i magazynów wegla. Równoczesnie celem wynalazku jest zmniejszenie wytrzymalosci mechanicznej górotworu i wegla w postaci calizny, co eliminuje zagrozenia zwiazane z akumulacja energii i poprawia urabialnosci skaly, zmiejszajac ilosc frakcji drobnych szczególnie pylistych.The aim of the invention is to prevent the formation of oxidation-reduction reactions in carbon by increasing the temperature, fires and fires of dumps and coal stores. At the same time the goal The invention is to reduce the mechanical strength of the rock mass and carbon in the solid form, which is eliminated dangers associated with the accumulation of energy and improves the workability of the rock, reducing the number of fine fractions especially dusty.
Istota rozwiazania sposobu preparacji wedlug wynalazku polega na wprowadzeniu do wegla lub górotworu mocznika lub jego roztworów wodnych, korzystnie z dodatkami zwiazków powierzchniowo czynnych.The essence of the preparation method according to the invention consists in introducing into coal or rock mass urea or its aqueous solutions, preferably with the addition of surfactants.
Sposób wedlug wynalazku w stosunku do znanych sposobów charakteryzuje sie dzialaniem inhibicyjnym w stosunku do mechanizmu i kinetyki reakcji fizyko-chemicznych zachodzacych w caliznie po przejsciu z trój- osiowego stanu naprezen calizny. Szczególnie dotyczy on zahamowania aktywnosci wegla in statu nascendi pochodzenia weglowodorowego w srodowisku wody i tlenu atmosferycznego. Jednoczesnie na skutek reakcji fizyko-chemicznych z osnowa nieograniczna, szczególnie wegla spowodowane jest obnizenie wytrzymalosci mechanicznej calizny, co równoznaczne jest z lokalnym odprezeniem w calej masie. Wazna równiez zaleta sposobu wedlug wynalazku jest zmniejszenie pylenia w trakcie urabiania preparowanej calizny oraz zmniejszenie wybuchowosci pylów weglowych. Dodatkowa cecha jest zlikwidowanie zagrozenia pozarowego wegla umieszczo¬ nego na zwalowiskach. Spalany wegiel po preparacji wykazuje wyzsza kalorycznosc ze wzgledu na zmniejszenie ilosci wody miedzykrystalicznej, natomiast utleniona siarka reaguje w spalinach z produktem termicznego rozkladu mocznika tworzac siarczan amonowy, który eliminuje emisje szkodliwych tlenków siarki.2 100 748 Przyklad I. W pokladzie eksploatowanym na zawal na spag nanosi sie mocznik w postaci stalej w ilosci 0,2 kg/m2# po czym przesuwa sie obudowe powodujac zawal, przy czym resztki wegla ze stropu opadaja na powierzchnie pokryta mocznikiem.The method according to the invention is characterized by an inhibitory effect in relation to known methods in relation to the mechanism and kinetics of physico-chemical reactions taking place in the body after the transition from of the axial state of stress. It especially concerns the inhibition of the activity of carbon in statu nascendi hydrocarbon origin in the environment of water and atmospheric oxygen. Simultaneously as a result of a reaction Physico-chemical materials with an unlimited matrix, especially carbon, is caused by a reduction in strength mechanical body, which is equivalent to local relaxation in the whole mass. An important advantage as well of the method according to the invention is to reduce the dusting during mining of the prepared flake and to reduce it explosion of coal dust. An additional feature is the elimination of the fire hazard of the coal on the dumps. Burned coal after preparation shows a higher caloric value due to the reduction the amount of intercrystalline water, while the oxidized sulfur reacts in the exhaust gas with the thermal product decomposes urea to form ammonium sulphate, which eliminates the emission of harmful sulfur oxides. 2 100 748 Example I. Solid urea is applied to the spag in the seam exploitation in the amount of 0.2 kg / m2 # then the casing is shifted causing a collapse, with the remnants of carbon from the ceiling falling on urea-coated surfaces.
Przyklad II. W pokladzie eksploatowanym na zawal na spag nanosi sie wodny roztwór mocznika o stezeniu 500 g/l w ilosci 4 litry na 1 m2.Example II. In the deck exploited during the collapse, an aqueous urea solution is applied to the spag at a concentration of 500 g / l in the amount of 4 liters per 1 m2.
Przyklad III. Na zwal wegla o powierzchni 2000 m2 i wysokosci 2 m nanosi sie mocznik w postaci stalej w ilosci 0,1 kg na 1 m2.Example III. On a coal pile with an area of 2000 m2 and a height of 2 m, urea is applied in the form of fixed in the amount of 0.1 kg per 1 m2.
Przyklad IV. Na zwal wegla o powierzchni 2000 m2 i wysokosci 2m nanosi sie 5 l/m2 wodnego roztworu mocznika o stezeniu 700 g/l.Example IV. On a coal pile with an area of 2000 m2 and a height of 2 m, 5 l / m2 of water is applied urea solution at a concentration of 700 g / l.
Przy k l ad V, Do otworów wykonanych w caliznie weglowej, górotworze bedacym przerostem kamien- no-weglowym lub w postaci piaskowca o odleglosci 50 m i srednicy 60 mm wprowadza sie mocznik w postaci roztworu o stezeniu 100 g/l w ilosci 2000 I do kazdego otworu.Example V, For holes made in a coal bed, a rock mass that is coal or sandstone with a distance of 50 m and a diameter of 60 mm, urea in the form of solution of 100 g / l in the amount of 2000 l for each hole.
