Abstract: Изобретение относится к горному делу, а конкретно к технологии разработки мощных пожароопасных угольных пластов. Задачей изобретения является повышение безопасности и повышение производительности за счет установления рациональных параметров наклонных слоев при одновременной их отработке в восходящем порядке. Способ разработки мощных пологих угольных пластов с труднообрушаемыми породами кровли включает отработку одновременно двумя наклонными слоями в восходящем порядке длинными столбами с опережением верхнего слоя нижним на величину зоны активного сдвижения горных пород с отработкой обоих слоев на выработки нижнего с последующим их погашением. При отработке нижнего (подсечного ) слоя угольный массив верхнего слоя в плоскости, проходящей по линии контакта штрека и очистного забоя, разупрочняют в зоне работы очистного комплекса либо путем взрывания шпуровых зарядов ВВ камуфлетного типа, либо методом гидроразрыва пласта. Мощность нижнего (подсечного) слоя выбирают исходя из коэффициента кратности слоев К = М ВС /М НС  в пределах 2,2-3,8, а мощность верхнего слоя принимают не менее величины, определяемой из выражения М ВС  ≥ М НС /(К Р -1), где М ВС  - мощность верхнего слоя, м; М НС  - мощность нижнего слоя, м; К Р  - коэффициент разрыхления угля, равный 1,4. 2 з.п·. ф-лы, 3 ил.

Abstract: FIELD: petroleum processing. 
     SUBSTANCE: invention relates to production of fuel fractions from liquid hydrocarbon feedstock and to oxidative purification of these fractions to remove sulfur compounds. Process is carried out by oxidizing feedstock with nitric acid or nitric acid/hydrogen peroxide mixture at 40-140 о С and pressure up to 1 MPa, after which aqueous layer is separated from hydrocarbon layer, low-molecular oxidation products are extracted from hydrocarbon feedstock by polar solvents and feedstock fractioned. In the latter operation, high-molecular oxidation products remain in still residue (mazut). For 1 mole sulfur, 0.6 to 2 mole nitric acid is used with concentration 35-99.5% and content of 0.05 to 2.0% nitrogen oxide calculated as NO 2 . Mixture HNO 3 /H 2 O 2  is taken such as to provide 0.3 to 1.5 mole active oxygen per 1 mole sulfur. Polar extractants are selected from sodium hydroxide, carbonate, and sulfate aqueous solutions, glycols, ethanolamines, dimethylformamide, cellosolves, acetone, isopropyl alcohol, and mixtures thereof. Petroleum-origin sulfoxides and sulfones are separated from extract using known techniques.
