FIELD: oil processing industry. ^ SUBSTANCE: method includes feeding of combustible oxidizing compound into bed treatment area, which compound contains ammonia nitrate, urea, nitric acid, acetic acid and water, feeding of igniting material pressed in form of tablets into area of combustible oxidizing compound location, and, additionally, feeding of gunpowder charge of solid-fuel material made of ballistic gunpowder or ballistic converted artillery gunpowder, or of compound fuel containing ammonium perchlorate as oxidizer, with later extraction of bed, while charge is inserted into area of bed treatment either after feeding of combustible oxidizing material and insertion of igniting material into it, or before feeding of combustible oxidizing material and insertion of igniting material into it, or concurrently with igniting material, as which is used at least one of following row: calcium hydride, magnesium hydride, barium hydride, titanium hydride, aluminum, with amount of the latter in mixture of said hydrides 10-50% of mass, igniting material is used in amount no more than 5.0% of combustible oxidizing material mass. Combustible oxidizing material includes, in percents of mass: ammonia nitrate 30-50, urea 10-30, nitric acid 4.0-6.0, acetic acid 4.0-6.0 and water up to 100. In combustible oxidizing material no more than 10% of mass of hydrochloric acid, and with concurrent insertion of igniting material and charge the latter is placed either above, or below, or between igniting material tablets. ^ EFFECT: higher efficiency. ^ 4 cl, 1 tbl
