Description

The invention relates to mining, specifically to temporary fuse HbiM m for preparatory workings of mining and coal mines,

Known safety lining, including the upper, protective visor, hydraulic cylinders and spacers lj.

The disadvantages of this CR1.: 1-and are the considerable complexity of its installation and the impossibility of application in the workings, carried out with the use of anchor lining.

Closest to the invention of the technical essence and the achieved result is a safety ceiling support, including a box-shaped top, a protective visor, power cylinders and a support device zl.

The disadvantage of such lining is considerable labor-intensive work when it is used in workings with anchor lining, are carried out; drilling and blasting method, associated with the need to make grooves in the sides of the excavation to install the support device, as well as the lack of protection against the dynamic effects of blasting,. .

The aim of the invention is to reduce the complexity of its use in workings with anchor, held by the drilling method.

This goal is achieved by the fact that in a protective ceiling lining, including 1 Lorobchaty top, a protective visor, power cylinders and a support device, the latter is made as open from the side opposite the face of the grips that are hingedly attached to the side surface of the box top, the protective visor is provided with guide sleeves and a screen mounted at an acute angle on its downhole face, and the visor is fitted / filled with openings for the sleeves and placed inside the box with the possibility of pulling in through forces O cylinder,

1 shows a fuse on the ceiling lining, top view, in FIG. 2, the same, side view.

Safety ceiling lining consists of a box-shaped top 1, VYPP1GZHNOGO protective visor 2 with a screen - a thick metal sheet 3 (to protect against dynamic loads during an explosion) installed at an acute angle at the downhole end of the visor, To the box top ka 1 and retractable visor 2 attached the power cylinder 4 (FIG. 2) for extending the safety support. In the retractable visor 2, guide sleeves 5 are inserted through which drilling for anchoring is performed. On the lateral surfaces of the box top 1 and retractable visor 2 on the vertical axis x 6 us-Taiovlena folding grips 7 with grooves 8, open from the side opposite to the face. Safety lining using anchor lining 9 is suspended from the roof of the excavation (Fig, 2).

Safety ceiling lining works in the following manner,

With the help of anchor lining 9 (Fig, 2), the safety ceiling lining is suspended to the roof of the excavation. The rod of the power cylinder 4 (Fig. 2) is retracted and the retractable visor 2 is inside the top box 1. When the power cylinder 4 expands, the stem of the latter pushes the retractable visor 2, after fully extending through the guide sleeves 5 and the grooves 8 of the hinge clamps 7 t the roofing under the anchor lining 9. The latter is installed only for folding clamps 7, and in the remaining holes the anchor lining is installed after they appear behind the shifted safety lining. When the power cylinder is contracted, the top box 1 slides over the retractable visor 2, and its folding arms 7 come off the anchors 9. In this case, the folding arms 7 rotate on vertical axes 6 inside the top box. Thus, the preliminary lining is again in its original position, suspended from the roof by anchors through the folding arms 7 of the retractable visor. After this, the upper grips of the roof box 7 are turned back into the initial position and the anchor bolts 9 are installed. Then, when the power cylinder 4 is moved apart and the visor 2 is extended, the clamps 7 are folded back from the flap 9 after the visor has been extended. repeated sheaf

In a illogical manner, move the adjacent soktsin (if any). At the same time, this movement can be carried out sequentially, as well as simultaneously with the pew section. Thus, the maintenance of the roof in the bottomhole zone and the installation of anchor supports is carried out simultaneously. The application of the proposed safety support does not interfere with the use in the face of the production of drilling rigs and loading-hauling machines.

The use of safety ceiling lining will improve the safety of work in the face, will improve working conditions, as well as reduce the time for bringing the slaughter to a safe state and, therefore, will increase

rate of penetration.
