Abstract: FIELD: electrical engineering, power supply sources of electric filters presenting capacitive loads. SUBSTANCE: optimal electric circuit of facility makes it feasible to form alternating voltage across capacitive load ( electric filter ) on which pulse voltage is superimposed. Developed circuit has high-voltage rigidly controlled electron-beam switches to form alternating voltage and softly controlled switches ( for instance, hydrogen thyratrons ) to form additional pulse voltage. Circuit combines advantages of source of alternating and pulse power supply. Amplitude of pulse voltage changes with the aid of rigidly controlled electron-beam valve by change of width of controlling pulse. Use of separate discharge inductance and recuperation inductance allows leading and trailing front of pulse voltage of different length to be obtained. Common control system ensures any specified algorithm of operation to generate maximum possible efficiency of dust cleaning.

Abstract: Изобретение относится к области горной промышленности и может быть использовано для подземной разработки мощных рудных месторождений при массовых обрушениях массива горных пород в выемочных блоках. Задачей изобретения является снижение сейсмического воздействия ударной волны для обеспечения сохранности выработок, скважин, шахтных коммуникаций и оборудования в смежных блоках, предотвращение передачи на массив горных пород дополнительных напряжений. Задача достигается тем, что при вскрытии и подготовке мощных рудных месторождений рудное тело по простиранию разделяют на выемочные единицы (блоки). В каждом блоке на нижнем горизонте подготавливается комплекс подготовительно-нарезных выработок, на верхнем горизонте подготавливается комплекс буровых выработок. Компенсационную камеру формируют со смещением от контакта со смежными блоками, а на границе со смежными блоками создают вертикальную защитно-экранирующую щель путем разбуривания рудного массива из буровых выработок нисходящими и восходящими скважинами в вертикальном направлении, зарядкой указанных скважин зарядами ВВ и взрыванием скважинных зарядов. Щель образуют с формированием вертикального контакта из уплотненной среды на всю высоту блока. Скважинные заряды указанной щели взрывают с короткозамедленным опережением по отношению к скважинным зарядам, расположенным между компенсационной камерой и смежными блоками. Образованная уплотненная горная масса в защитно-экранирующей щели служит демпферным слоем, защищающим смежный блок, а соответственно расположенные в нем буровые и подготовительно-нарезные выработки, коммуникации и оборудование от воздействия ударных (сейсмических) волн. 3 ил.
