Description

Изобретение относитс к горной (промышленности и может быть использовано при подземной разработке месторождений полезных ископаемых с закладкой выработанного пространства.The invention relates to the mining (industry and can be used in underground mining of mineral deposits with the laying of the goaf.

Известен способ гидравлической закладки выработанного пространстваi заключающийс в приготовлении гидросмеси , транспортировании ее по магистральному трубопроводу до илрабо .тайного пространства и по забойному закладочному трубопроводу в пределах выработанного пространства. При этом в процессе закладочного массива производ т периодические остановки гидротранспорта и укорачивание забойного закладочного массива 1.There is a method of hydraulic laying of the developed space, which consists in preparing the slurry, transporting it through the main pipeline to the Ilrabot secret space and along the bottomhole logging pipeline within the developed area. At the same time, in the process of a backfill array, periodic hydrotransport stops and shortening of the downhole backfill array 1 are made.

Недостатками такого способа вл ютс высока трудоемкость и низка производительность закладочных работ вследствие периодических остановок и укорачивани трубопровода.The disadvantages of this method are high labor intensity and low filling capacity due to periodic shutdowns and shortening of the pipeline.

Кроме того, известен способ Гидравлической закладки наклонных камер при подземной разработке месторождений полезных ископаемых, заключаки41 йс в приготовлении закладочной гидросмеси, доставке ее по магистральному закладочному трубопроводу до камеры, подаче гидросмеси в камеру иIn addition, there is a known method of Hydraulic laying of inclined chambers during underground mining of mineral deposits, which are concluded in preparing backfill slurry, delivering it via the main backfill pipeline to the chamber, feeding the slurry into the chamber and

отводе отработанной воды по предварительно проложенному по наклонной почве камёЕы дренажному трубопроводу за пределы камеры. При этом нг1мыв закладочного массива производ т путем подачи гидросмеси самотеком по наклонной почве камеры 2.discharging waste water through a drainage pipeline previously laid on a sloping soil of the chamber. In this case, the ng1 wash of the filling mass is produced by feeding the slurry by gravity through the inclined soil of the chamber 2.

Недостатками известного способа вл ютс расслоение закладочного ма10 териала и недозакладка камер при уменьшении угла наклона почвы и кровли камеры, что приводит к снижению несущей способности закладочного массива.The disadvantages of this method are the separation of the backfill material and the underfitting of the chambers while reducing the angle of inclination of the soil and the roof of the chamber, which leads to a decrease in the carrying capacity of the backfill array.

Цель изобретени - улучшение заполнени камеры и повышение несущей способности закладочного массива за счет более равномерного распределени закладочного материала при умень20 шении угла наклона почвы и кровли камеры.The purpose of the invention is to improve the filling of the chamber and increase the carrying capacity of the filling mass due to a more even distribution of the filling material while reducing the angle of inclination of the soil and the roof of the chamber.

Поставленна цель достигаетс тем, что перед подачей в камеру гидросме25 си к наклонной кровле камеры вдоль ее продольной оси прикрепл ют транспортный желоб, который соедин ют с магистральным закладочным трубопроводом, и производ т подачу гидросмеси в The goal is achieved by attaching a transport chute to the inclined roof of the chamber along its longitudinal axis, which is connected to the main backfill pipeline, and fed to

30 камеру по указанному желобу.30 camera on the specified chute.

Claims

The claims a along a sloping post lay drainage 3 and 3 perforated installation of insulating vehicle

The drawing shows a diagram of the filling of the slurry-tilted chamber, a vertical section.

A transport chute 2 is attached to the inclined roof of the chamber 1 along its longitudinal axis, and a pipe ’pipe’ is attached to the chamber 1. After the lintels 4 and the chute 2 with the main filling | pipe 5, the hydraulic mixture is supplied into the chamber along the chute

2. As the chamber fills, the hydraulic mixture overflows through the chute 2, which ensures filling of the chamber under the roof. Wastewater 6 through the drainage pipe 3 is discharged outside the chamber 1. The laying of the chamber of the proposed method allows to reduce the spreading length of the hydraulic mixture and to minimize the stratification of the filling mass by size along the length of the wash. At the same time, the spreading length of the slurry stream is equal to the slope on the other, which ensures minimal stratification of the filling mass.

The proposed method makes it possible to ensure uniformity of the filling array along the length of the washout, more complete filling of the chamber under the roof at reduced angles of inclination of the soil and the roof of the chamber, to reduce cement consumption during hardening, and to eliminate the cost of re-filling voids.

The method of hydraulic laying of inclined chambers during underground mining; useful deposits of iskoyashkh, which consists in preparing the filling slurry, delivering it through the main laying pipe to the chamber, supplying the slurry to the chamber and discharging waste water through the drain pipe previously laid along the inclined chamber of the chamber outside the chamber, which is characterized by the fact that in order to improve the filling of the chamber and increase bearing capacity zag. masonry array due to a more uniform distribution of the filling material with a decrease in the angle of inclination of the soil and the roof of the chamber, before feeding the slurry into the chamber, a transport chute is attached to the sloping roof of the chamber along its longitudinal axis, which is connected to the main filling pipeline, and the slurry is fed through the specified pipeline.
