Способ закладки камер осуществилют следующим образом.The method of laying cameras is as follows.

При заполненных сплошным mhcchbqm твердеющей смеси смежных первичных камер 1 над вторичной камерой 2 предварительно (до ее обработки) проходят закладочные выработки 3 и 4, предназначенные для прокладки трубопровода и транспортирования по нему твердеющей смеси и доставки сухой породы самоходным оборудованием или конвейерным транспортом.When the adjacent primary chambers 1 are filled with continuous hardening mixture mhcchbqm above the secondary chamber 2, preliminary workpieces 3 and 4 are passed before it is processed, intended for laying the pipeline and transporting the hardening mixture along it and delivering dry rock with self-propelled equipment or conveyor transport.

Повторяющимися направленными взрывами породу потолочины 5 полевого орта 6 укладывают в траншейное днище камеры 2, создавая этим условие для поступления отбитой и замагазинированной руды в торец выработки, где ее грузят самоходным оборудованиемПо окончании выпуска руды и укладки породы в днище камеры 2 в нижних заездах 7 возводят изолирующие перемычки 8 с дренажными отверстиями.By repeating directed explosions, the rock of the ceiling 5 of the field ort 6 is placed in the trench bottom of chamber 2, thereby creating the condition for the beaten and stained ore to enter the end of the mine, where it is loaded with self-propelled equipment. jumpers 8 with drainage holes.

По трубопроводу в выработке 4 и пробуренные из нее скважины 9 подают закладочный раствор на уложенную взрывом породную массу (подушку)- 10 . для заполнения ее пор и уплотнения.Through the pipeline in the development 4 and the wells 9 drilled from it, the filling mortar is supplied to the rock mass (cushion) laid by the explosion - 10. to fill its pores and seal.

В следующей стадии работ проходят восстающие 11 и через них перепускают сухую породу до образования навалов враспор с кровлей. Место проведения восстающих 11 определяют с учетом возведения искусственного массива, обладающего заданной устойчивостью обнажаемой стенки, между контуром навала породы и панельным целиком 12, подлежащим в последующем выемке.In the next stage of work, rebellious 11 go through and pass dry rock through them until the formation of bulk piles with the roof. The venue of the uprising 11 is determined taking into account the construction of an artificial array with a given stability of the exposed wall, between the contour of the bulk of the rock and the entire panel 12, to be subsequently excavated.

В дальнейшем одновременно заполняют открытое пространство камеры: в ее торцах за навалами сухой породы через скважины 9 и верхние заезды 13; в ее средней части между навалами через продольную щель 14, которую образуют бурением и взрыванием нисходящих вертикальных скважин по мере укладки определенного объема породы.In the future, at the same time, they fill the open space of the chamber: at its ends behind the bulk of dry rock through the wells 9 and the upper races 13; in its middle part between the bulk through a longitudinal slit 14, which is formed by drilling and blasting downward vertical wells as a certain volume of rock is laid.

В торцы камер 2 одновременно подают закладочный раствор через скважины 9 и сухую породу через верхние панельные штреки и заезды 13 из них. При достижении закладочным раствором уровня почвы заездов 13 в них устанавливают перемычки. Среднюю часть камеры 2 заполняют сухой породой, доставляемой из проходческих забоев или с отвалов на поверхности, а также взрываемой в объеме щели.At the ends of the chambers 2, the filling mortar is simultaneously fed through the wells 9 and the dry rock through the upper panel drifts and races 13 of them. When the filling level of the soil level reaches races 13, jumpers are installed in them. The middle part of the chamber 2 is filled with dry rock delivered from sinking faces or from dumps on the surface, as well as exploding in the gap volume.

При подаче твердеющей смеси в торцы камеры 2 ее уровень выдерживают таким, чтобы она не протекала за навалы пород.When supplying a hardening mixture to the ends of the chamber 2, its level is maintained so that it does not leak over bulk rocks.

В последней стадии работ верхнюю часть камеры 2 по периметру, т.е.In the last stage of work, the upper part of the chamber 2 around the perimeter, i.e.

3® пространство вокруг сухой породы, заполняют твердеющей смесью3® space around dry rock, filled with a hardening mixture

Claims

1 The invention relates to the mining industry and can be used in the development of gently dipping deposits with the laying of a high-bottomed space. The purpose of the invention is to intensify the bookmarking process while reducing the cost of backfilling. FIG. Figure 1 shows the laying of a field orm ceiling at the bottom of a chamber; in fig. 2 shows a section A-A in FIG. 1 in FIG. 3 - laying hardening mixture on the loosened rock; in FIG. 4 a section BB in FIG. 3; in fig. 5 - formation of rock piles; in fig. 6 - filling the middle and bargaining chamber; in fig. 7 is a section bb of FIG. 6. The method of camera laying is carried out as follows. When the hardening mixture filled with continuous MaccnBQM and adjacent primary chambers 1 are filled above the secondary chamber 2, filling holes 3 and 4 are preliminarily (before it is processed) to lay the pipeline and transport the hardening mixture through it and delivery of dry rock by self-propelled equipment or conveyor transport. Repeated directional explosions of the rock of ceiling 5 of the field orth 6 are placed in the trench bottom of chamber 2, creating a condition for the return of broken and maged ore to the end of the mine, where it is loaded with self-propelled equipment. 2 in the lower heats 7, insulating bridges 8 with drainage holes were erected. The pipeline in the excavation 4 and the wells 9 drilled from it feed the filling solution onto the rock mass (cushion) 10 laid with the spring to fill its pores and seal it. In the next stage of the work, 11 rebels pass and pass dry rock through them before forming a pile with a roof. The location of the rebels 11 is determined taking into account the construction of an artificial array with a given stability of the exposed wall, between the rock pile contour 112 and the entire panel 12, which is subject to subsequent excavation. Later on, the open space of the chamber is simultaneously filled: at its ends, behind the piles of dry rock through wells 9 and upper races 13; in its middle part between the bulk through the longitudinal slit 14, which is formed by drilling and drilling down a 1 x vertical well as a certain volume of rock is laid. In the ends of the chambers 2 at the same time serves the filling solution through the wells 9 and dry rock through the upper panel drifts and arrivals of 13 of them. When the filling solution reaches the level of the soil of the races 13 in them, jumpers are installed. The middle part of chamber 2 is filled with dry rock, delivered from tunnel faces or from dumps on the surface, as well as a gap exploded in the volume. When feeding hardening mixture in the ends of the chamber 2, its level is maintained so that it does not flow over the pile of rocks. In the last stage of works, the upper part of chamber 2 along the perimeter, i.e. the space around the dry rock is filled with a hardening mixture. The invention The method of laying chambers, including the drilling of backfilling workings, drilling wells from them to supply the filling solution and carrying out drilling dp to feed the rock, feeding the rock to the bottom of the chamber to form cones and then simultaneously feeding the filling solution to the peripheral parts of the chamber and the rock to the center This is due to the fact that, in order to intensify the laying process while reducing the cost of backfilling, before feeding the rock they form a rock cushion by breaking the bottom of the chamber, the rock is fed to the backwater by the formed cones of the roof of the chamber, and the rock is fed to the central part of the chamber through a slit formed in the roof of the chamber successively.
