Description
подушку с последующей переэкскавацией части предотвала на тесодержащие породы .pillow followed by re-extraction of the part of the predal to the rock containing rocks.
На фиг. 1 показан поперечный профиль; на фиг. 2 - план разреза.FIG. 1 shows a transverse profile; in fig. 2 - plan of the cut.
Отработку верхнего 1 и нижнего 2 междупластий производ т экскаватором за один рабочий ход с 1одшагиванием. Взрывные работы ведутс одновременно по обоим междупласть м . При своем ходе экскаватор производит операции в следующей последовательности: перемещает породы нижнего междупласть 2 во временный навал (предотвал ) 3, отсыпает предохранительную подущку 4, размещает на ней углесодержащие породы 5 верхнего междупласть 1, которые затем изолирует инертными породами 6 .из предотвала 3 с оставлением части пород предотвала в качестве предохранительного буфера 7, отдел ющего угольный пласт 7 от углесодержащих пород отвала.The development of the upper 1 and lower 2 interdustries is carried out by an excavator in one working stroke with 1 stepping. Blasting operations are carried out simultaneously on both sides. During its course, the excavator performs operations in the following sequence: it moves the rocks of the lower interplast 2 into a temporary pile (front shaft) 3, pours the safety sheet 4, places carbonaceous rocks 5 on it of the upper interplast 1, which then isolates the inert rocks 6. parts of the rocks were prefixed as safety buffer 7 separating the coal seam 7 from the coal containing rocks of the dump.
Отсыпка углесодержащих пород за предотвал на предохранительную подушку, состо щих из инертных пород, поверхностна изол ци углесодержащих пород инертными породами предотвала с оставлением части предотвала как предохранительного буфера, осуществл емые за один рабочий ход экскаватора , предотвращают доступ воздуха к углесодержащим породам, что исключает возможность возникновени эндогенных пожаров во внутреннем отвале и распространени этих пожаров на угольный пласт.Charging coal-bearing rocks for prefilling a safety cushion consisting of inert rocks, precursor insulation of coal-bearing rocks with inert rocks prevented leaving part of the preheat as a safety buffer, made during one working stroke of the excavator, preventing access of air to coal-bearing rocks, which eliminates the possibility of endogenous fires in the internal dump and the spread of these fires to the coal seam.
