发明名称 FILLING MIXTURE FOR FILLING ABANDONED WORKIMGS OR MAKING AN ARTIFICAL ROOF
摘要 1. A filling mixture for filling mining voids, or for making an artificial roof, which is a variant of a mixture according to the invention under the patent number 143 339, transported gravitationally in traditional filling installations leading to headings from the filling funnel on the surface to the selected area of the bed under exploitation, or to the rock waste for the purpose of building an artificial roof over the lower located bed layer, containing at the inlet of the filling funnel from 75 to 95 per cent by volume of solid parts on the carrier from flotation waste containing preferably above 500 grams of solid parts in a litre of flotation waste and moisture binding chemical substances, having a homogeneous form and/or composed of several components fed to the mixture preferably before the inlet to the selected area of the bed in proportion to the volume of the supplied mixture for completely filling the selected area, characterised in that in its variant containing from 70 up to 95 percent by mass of solid parts in the carrier in the form of quick clays and other components forming clay muds of liquid consistency per litre of the mixture to which fillers are added in quantity of 1 to 15 per cent, most preferably 1 to 10 per cent of solid parts to be chemical substances which bind a part of a water content, most preferably in the form of a smoke-box dust, or power station ash, to obtain from 900 to 1,100 grams of solid parts in one litre of the mixture with the carrier in the form of quick clays, bentonites, or clay muds originated from biodegradation of organic substances in homogeneous form, or in non-homogeneous form built-up of fillers in proportionally selected quantities from 450 up to over 500 grams at the inlet to the filling funnel, containing in its composition quantities equal to or lower than 50 per cent of fillers consisting of flotation waste and quick clays, or clay waste, and also in quantity equal to or lower than 50 per cent of fillers made up of smoke-box dust, waste stone, and blast furnace slag in quantities of 40 to 60 per cent and of the most favourable granulation, whereas the blast furnace slag accounts forup to 30 percent of the total content of fillers in the mixture.
