Description
Technical field
The present invention relates to a kind of erosion control safety methods of Coal Face Passing Through connection roadway.
Background technique
The erosion control of working face and connection roadway safety, is always the most important thing in colliery industry coal mining trouble free service, work
There is many unsafe factors in face and connection roadway, the erosion control of Coal Face Passing Through connection roadway is never obtained safely well
It solves.
Summary of the invention
To overcome the shortcomings of existing technologies, the present invention provides a kind of erosion control safety method of Coal Face Passing Through connection roadway, this hair
Bright technical solution is:
The following steps are included:
(1) the erosion control release of Coal Face Passing Through connection roadway: A helps benefit before and after the two crossheading connection roadway of working face in tunnel within the scope of 150m
Implement portion, side unloading pressure by blasting, spacing 10m, hole depth 15m with pressure relief vent;During B Coal Face Passing Through connection roadway, help in track crossheading two and
First advance 300m range is helped to implement large diameter borehole release, hole depth 25m, bore diameter 125mm, pitch of holes in adhesive tape crossheading
No more than 1m；Construction hole depth 35m, side portion's pressure relief vent of spacing 2m are helped outside C face belt crossheading；During crossing connection roadway, in advance
Working face 300m one hole depth 25m of complement, pressure relief vent of aperture 125mm among former pressure relief vent；
(2) working face cuts a pressure relief method: working face slipping tail away from connection roadway 30m at, construct towards connection roadway direction in work
Pressure relief vent, hole depth 25m, spacing 2m, sequence of construction are constructed from work towards a direction is slipped；
(3) monitoring and warning processing method during Coal Face Passing Through connection roadway: A reinforces working face and connection roadway stress monitoring, tunnel are received
Deformation monitoring is held back, monitoring data are regularly published, when there is early warning or monitoring data anomalous variation, controls face propulsion speed,
Advance of the face degree is controlled in 3 knives/day, to connection roadway construction pressure relief vent in working face；There is stress in two crossheading of B working face
When early warning, cleaning bottom of hole release, pitch of holes 2m, hole depth 25m are carried out before and after the prewarning area at 15M；There is big face in two crossheading of working face
When product stress early warning, face propulsion speed is controlled, by the control of advance of the face degree in 3 knives/day, is carried out in two crossheading of working face
Cleaning bottom of hole release；During C Coal Face Passing Through connection roadway, micro seismic monitoring data are handled in time；Working face day, which releases energy, reaches 5*104J
When, limited production processing is carried out to working face, notice working face slows down coal cutting speed, must not exceed 2 knives according to split run production, whole day is not
Be more than the production of 4 knife tissues, working face day releases energy when reaching 7*104J, carries out halt production processing, off-time to working face
It must not be lower than 2 hours, stablize until stope energy discharges, advanced stress variation without exception；
(4) implement limit person's access management method during Coal Face Passing Through connection roadway；When working face is apart from connection roadway 200m, to connection roadway
Closed management is carried out, anyone entrance is forbidden；During Coal Face Passing Through connection roadway, two crossheading of working face is super during working surface production
Forbid anyone entrance within the scope of preceding 300m；
(5) reinforce face timbering intensity, it is ensured that the setting load of fully mechanized mining supporter and two crossheading advance timberings reaches requirement.
The invention has the advantages that can preferably guarantee the erosion control safety of Coal Face Passing Through connection roadway by the release that drills；It is logical
It crosses monitoring and warning and reinforces face timbering intensity, can find the problem in time, carry out erosion control and prepare safely, mention to greatest extent
High economic benefit.
Specific embodiment
The invention will now be further described with reference to specific embodiments, the advantages and features of the present invention will be with description and
It is apparent.But examples are merely exemplary for these, and it is not intended to limit the scope of the present invention in any way.Those skilled in the art
Member it should be understood that without departing from the spirit and scope of the invention can details to technical solution of the present invention and form into
Row modifications or substitutions, but these modifications and replacement are fallen within the protection scope of the present invention.
The present invention relates to a kind of erosion control safety methods of Coal Face Passing Through connection roadway, comprising the following steps:
(1) the erosion control release of Coal Face Passing Through connection roadway: A helps benefit before and after the two crossheading connection roadway of working face in tunnel within the scope of 150m
Implement portion, side unloading pressure by blasting, spacing 10m, hole depth 15m with pressure relief vent;During B Coal Face Passing Through connection roadway, help in track crossheading two and
First advance 300m range is helped to implement large diameter borehole release, hole depth 25m, bore diameter 125mm, pitch of holes in adhesive tape crossheading
No more than 1m；Construction hole depth 35m, side portion's pressure relief vent of spacing 2m are helped outside C face belt crossheading；
(2) working face cuts a pressure relief method: working face slipping tail away from connection roadway 30m at, construct towards connection roadway direction in work
Pressure relief vent, hole depth 25m, spacing 2m, sequence of construction are constructed from work towards a direction is slipped；
(3) monitoring and warning processing method during Coal Face Passing Through connection roadway: A reinforces working face and connection roadway stress monitoring, tunnel are received
