Abstract
Изобретение относитс к горному делу и м.б. использовано при подземной разработке угольных пластов. Цель - повышение произв-сти проходческих работ и устойчивости вскрывающих выработок. Дл этого предварительно отрабатывают запасы угл под местом заложени стволов лавами. Затем провод т блоковые стволы (БС) в разгру- женных лавами зонах и выработки околоствольного двора. Причем последние на горизонте отработки запасов угл сооружают до проходки на него БС. Проведение БС начинают после снижени деформации толщи пород в месте заложени его до уровн , допустимого дл крепи указанного БС. 2 ил, № tThe invention relates to mining and m. used in underground coal mining. The goal is to increase the production of tunneling works and the stability of the opening workings. For this purpose, coal reserves are preliminarily worked out under the place where the trunks are laid by lavas. Then, block trunks (BS) are carried out in the areas unloaded by lavas and the development of the near-barrel yard. Moreover, the latter on the horizon, the mining of coal is constructed before the BS is driven to it. The BS is started after the deformation of the strata of rocks in the place of its foundation has been reduced to the level acceptable for the support of the specified BS. 2 silt, № t
Description
Изобретение относитс к горному делу и может быть использовано при подземной разработке угольных пластов.The invention relates to mining and can be used in underground mining of coal seams.
Цель изобретени - повышение производительности проходческих работ и устойчивости вскрывающих выработок.The purpose of the invention is to increase the productivity of tunnel works and the stability of opening workings.
На фиг. 1 приведена технологическа схема осуществлени способа; на фиг. 2 - разрез А-А на фиг. 1.FIG. 1 shows a flow chart of the method; in fig. 2 shows section A-A in FIG. one.
Способ осуществл ют следующим образом .The method is carried out as follows.
С пройденных ранее стволов или с выработок соседней шахты посредством полевых 1-4 и пластовых 5 и 6 выработок и разгрузочной лавы 7 осуществл ют предварительную отработку запасов, расположенных в пределах охранного целика под ствол 8.From the previously drilled shafts or from the workings of the neighboring mine, by means of field 1-4 and reservoir 5 and 6 workings and discharge lava 7, preliminary stockpiling is carried out, located within the limits of the guard rear section 8.
Породу от проведени полевых и пластовых выработок размещают в выработанное пространство 9, что позвол ет, с одной стороны, избежать выдачи ее на поверхность и, с другой стороны, снизить деформации горных пород в районе промплощадки. С некоторым отставанием от разгрузочной лавы провод т выработки околоствольного двора 10, выполн ют рассечку сопр жени 11 со стволом и креп т их податливой или ограниченно податливой крепью.The rock from the field and reservoir workings is placed in the excavated space 9, which allows, on the one hand, to avoid its release to the surface and, on the other hand, to reduce rock deformations in the area of the industrial site. With some lag from the discharge lava, the mine workings of the near-barrel yard 10 are made, the cutting of the mating 11 with the barrel is performed and secured with their pliable or partially pliable lining.
Проходку ствола 8 начинают, когда деформаци подработанных пород снижаетс до значений, не опасных дл крепи ствола. Фактические значени деформаций подраVJThe penetration of the barrel 8 begins when the deformation of the waste rock decreases to values that are not dangerous for the trunk linings. Actual deformation values

батываемого массива устанавливают на основании инструментальных наблюдений на профильных лини х, оборудованных грунтовыми реперами в районе усть ствола 8 и в скважине 12 по глубинным реперам. После сбойки ствола с околоствольным двором сопр жение закрепл ют посто нной метал- ло-бетонной крепью.The batten massif is installed on the basis of instrumental observations on profile lines equipped with ground bench markers in the area of the mouth of the trunk 8 and in the borehole 12 along the depth reference points. After the barrel is connected to the near-barrel yard, the mating is secured by a permanent metal-concrete support.
Наличие околоствольного двора позвол ет дополнительно сократить сроки строительства комплекса, повысить скорость проходки ствола за счет применени комбинированной технологической схемы проведени ствола с использованием предварительно пробуренной скважины.The presence of a near-barrel yard makes it possible to further reduce the construction time of the complex, increase the speed of the borehole through the use of a combined technological scheme for conducting the borehole using a pre-drilled well.
П р и м е р. По оси ствола во врем разгрузочных работ бур т скважину 13 диаметром 0.8-1.5 м. Бурение можно осуществл ть как с поверхности, так и горизонта околоствольного двора. Затем скважину расшир ют до проектного сечени ствола с помощью буровзрывных работ.PRI me R. The wellbore 13 with a diameter of 0.8-1.5 m is drilled along the borehole axis during unloading. Drilling can be carried out both from the surface and the horizon of the near-wellbore yard. Then, the well is expanded to the design section of the wellbore by means of drilling and blasting.

Взорванна порода поступает в околоствольный двор, где ее с высокой производительностью убирают породопогрузочными машинами или скреперами и используют дл закладки выработанного пространства 9.The blown-up rock enters the near-barrel yard, where it is removed with high productivity by rock-loading machines or scrapers and is used for laying the developed space 9.
