Description

Изобретение относитс к горной промышленности и может быть использовано при подземной разработке полезных ископае-. мых дл образовани свободного пространства различной конфигурации в твердеющем закладочном массиве.The invention relates to the mining industry and can be used in the underground mining of mineral resources. to form free space of various configurations in a hardening stowing mass.

Известна опалубка дл образовани свободного пространства в виде выработки в твердеющем закладочном массиве, включающа замкнутую эластичную герметичную оболочку и штуцер со шлангом дл подвода в оболочку сжатого газа J1.Known formwork for the formation of free space in the form of excavation in a hardening filling mass, comprising a closed elastic hermetic casing and a fitting with a hose for supplying the compressed gas J1 to the casing.

Така опалубка может быть применена только в выработках небольшого объема с сформированием выработки круглого сечени между почвой и кровлей.Such formwork can only be used in workings of a small volume with the formation of a round section between the soil and the roof.

Известна также плавуча опалубка дл формировани горной выработки в твердеющей закладке, включающа эластичную замкнутую оболочку с каркасом в виде жестких колец, повтор ющих сечение выработки , и заполн емую прочным и более легким, чем закладочный материал, заполнителем , представл ющую собой модель формируемой горной выработки, и крепеж ,ные элементы дл подвески оболочки в выработанном пространстве 2.Floating formwork for forming mine workings in a hardening bed is also known, comprising an elastic closed shell with a skeleton in the form of rigid rings repeating the cross section of the work and filled with durable and lighter than filling material, a model of the work mine that is being formed, and fasteners for suspension of the shell in the goaf 2.

Недостатком указанной опалубки вл етс невозможность формировани одновременно нескольких сообщающихс между собой и расположенных па разных уровн х горных выработок.The disadvantage of this formwork is the impossibility of simultaneously forming several interconnected and located PA different levels of mine workings.

Целью изобретени вл етс формирование в твердеющей закладке одновременно нескольких горных выработок, сообщающихс между собой и располагающихс на 10 разных уровн х.The aim of the invention is the formation of several mine workings in a hardening bed at the same time, communicating with each other and located at 10 different levels.

Это достигаетс тем, что опалубка выполнена из отдельных соединенных между собой оболочек, элементы креплени каждой оболочки выполнены в виде гибких св зей соответствующей длины, одни концы которых соединены с каждой из оболочек, а другие снабжены кор ми, соединенными между собой.This is achieved by the fact that the formwork is made of separate interconnected shells, the fastening elements of each shell are made in the form of flexible ties of appropriate length, one ends of which are connected to each of the shells, and the others are provided with bark interconnected.

Claims

FIG. Figure 1 shows a diagram of the location of the elements of floating formwork in a hardening tab to form the generation of, for example, the lower hooking of the chamber; in fig. 2 is a diagram of the excavation of a mine working using a log cut formed by floating formwork, section A-A in FIG. I. The formwork consists of individual shells 1 made of elastic material and interconnected, for example, by means of hinges 2. Each form sheath has fasteners made in the form of flexible connections 3 of different lengths that connect the shells 1 to the crust 4 The armature is interconnected by means of distance flexible or rigid communication 5. The formation of workings in the hardening tab is carried out as follows. The spent chamber 6 is laid up to a certain level of hardening bookmark, and then through the control (inspection) passes, floating formwork elements are delivered, which consist of separate shells filled with light dense material, such as sawdust. A vent pipe can be used as the shell. Each element of the floating formwork is connected by means of a flexible connection with the bark 4. Adjacent elements of the floating formwork, representing a model of independent development, are interconnected by a hinge 2. Anchor between each other is connected by distance rigid or flexible links 5. After the floating formwork is installed, the waste chamber is laid down. As it is filled with the hardening tab, the formwork elements float to the level specified by the flexible link 3. To form an inclined bed, the flexible links 3 Formwork made in various lengths. Hard link 5 is necessary when installing the formwork in inaccessible for control areas of the chamber. Links 5 and 3 in combination of lengths determine the angle of the direction of the mountain Bbj operation. Once the filling mixture has hardened from the shell, the aggregate is removed and the production is ready. In order to expand the casing, the aggregate (sawdust) is removed from the hole to the depth of the drilled hole 7 and is broken. The presence of a cut-in cavity with a diameter of 500 mm improves the quality of blasting, the full use of holes 7 reduces the seismic effect on the surrounding massif. The presence of filler (sawdust) in the rest of the casing protects the cut cavity from being stitched. The shell for creating a cut is produced using compressed air, water or charge 8. The proposed formwork allows you to prepare the production in a hardening tab with minimal labor costs, reduce the degree of concrete destruction by the force of an explosion, allows using relatively simple materials, such as ventilation sleeves and sawdust, get ventilation development. Claims of the Invention Floating formwork for forming a mine working in a hardening bookmark, comprising an elastic closed shell with a lighter aggregate than the filling material, which is a model of the mine working being formed, and fasteners for hanging the shell in the worked out space, characterized in that in order to simultaneously form several mine workings, communicating with each other and located at different levels, the formwork is made of separate interconnected shells, The fastening elements of each shell are made in the form of flexible bonds of corresponding length, one ends of which are connected to each of the shells, while others are provided with cords rigidly interconnected.
