Abstract
The utility model discloses a protection facility used in the construction of a roadway in a mine, in particular to a coal roadway drill impermeable device for safety and protection when in coal roadway drilling. A wind drum (12) is movably arranged on the middle upper part of the side wall of the coal roadway, wind drum cloth (4) is arranged with a support steel tube (2) for building through a metal net (3), and is connected with rock and a coal bed (1), and a lifting rod (5) for building is movably supported on a support steel beam (11) of the two walls of the coal roadway. Since the impermeable device when in the two layers of protection drilling is designed, is firmly fixedly erected on the rock and the coal bed to be drill and is automatically adjusted to support, during the process of drilling the permeable rock and the coal bed, the utility model can prevent the underground water from instantly extruding and gas from overflowing, improves the safety factor during the working period, and has simple structure, safety, practicability, high efficiency and reliability.
Description
Technical field: the utility model relates to the protective equipment that uses when a kind of coal mine roadway is constructed, the coal road boring water proof device that safeguard protection is used when specifically being coal road boring.
Background technology: at present, in the construction of colliery, when especially the lithosphere that pervious layer is arranged being holed, because it is more open to blow out back rock, coal seam, operation is abnormally dangerous, accidentally just easily causes permeable casualty accident, has had a strong impact on construction safety.
The utility model content: the utility model has been avoided the easily permeable drawback that causes human casualty accident of the permeable lithosphere of former brill system, and providing a kind of can regulate automatically, improves the coal road boring water proof device of operating safety factor.Technical solutions of the utility model are achieved in that described air duct 12 is movably arranged on the middle and upper part of coal road sidewall, air duct cloth 4 is in the same place with supporting steel pipe 2 devices for building by wire lath 3, be connected with rock, coal seam 1, and with elevating lever 5 movable supporting for building on the supporting girder steel 11 of coal road two walls.
Effect of the present utility model is: because water permeable device when having designed two-layer protection boring, firmly fixed mount is located on rock to be holed, the coal bed, utilize rotary thrust to regulate support automatically, in boring the permeable rock of system, coal seam process, prevent that the instantaneous outstanding gas that reaches of underground water from overflowing, and improved the safety factor of duration of work, and it is simple in structure, safe and practical, high efficient and reliable, the permeable lithosphere that can be widely used in coal mine roadway bores system and blows out.
Description of drawings: Fig. 1 is a main sectional view of the present utility model
Fig. 2 is that the A-A of Fig. 1 is to view
The specific embodiment: embodiment 1: described air duct 12 is movably arranged on the middle and upper part of coal road sidewall, air duct cloth 4 is in the same place with supporting steel pipe 2 devices for building by wire lath 3, be connected with rock, coal seam 1, and with elevating lever 5 movable supporting for building on the supporting girder steel 11 of coal road two walls.Several steel buttons 10 of supporting steel pipe 2 usefulness for building firmly link together, and with elevating lever 5 movable supporting for building on the supporting girder steel 11 of coal road road two walls.Elevating lever for building 5 middle parts are provided with rotating handles 6.See Fig. 1, Fig. 2.
Embodiment 2: this device can not add air duct cloth 4 blowing out when using, and wire lath 3 is set before the air duct 12, and rubble splashes and hurts sb.'s feelings or smash air duct 12 and cable in the time of can preventing to blow out.
When construction, earlier air duct cloth and wire lath are linked together, again the two device is being used on the steel buckle device supporting steel pipe for building together, hold up near rock, coal bed, utilize rotating handles firmly to support with elevating lever for building then, its elevating lever for building lower end movable supporting is on the supporting girder steel of coal road two walls.Start rig 7, drive drilling rod 8, bore system boring 9 on rock, coal bed, underground water and gas can release from boring, by air duct gas are forced to discharge again.
Claims (3)
1. coal road boring water proof device, it comprises that air duct (12) is movably arranged on the middle and upper part of coal road sidewall, it is characterized in that air duct cloth (4) installs together by wire lath (3) and supporting steel pipe for building (2), be connected with rock, coal seam (1), and with elevating lever for building (5) movable supporting on the supporting girder steel (11) of coal road two walls.
