Description
Technical field
The present invention relates to a kind of coal mining gas drainage under suction processing technique, specially a kind of driving proof prominence optimization technique.
Background technique
It in high methane coal mining and tunnelling, needs to carry out the extraction of gas in advance, reduces watt in coal body
This content, to guarantee the safety of exploitation.It just needs first to carry out construction drill using drilling machine, in advance releases the gas in coal body
Come.The position of reasonable Arrangement drilling and quantity are to improve the important measures of gas drainage results.
In preparation group area (East north wing adhesive tape/transportation roadway north is dug) Construction Condition of certain mine.
(1) the reserve force East north wing adhesive tape/lane Fu Yun north pick 1100 meters or so regions in front are covered by the drilling of Yue Cheng mine km
It covers, more than extraction time 1 year and a half, the spacing of wells is 12--15 meters, amounts to 12,960,000 side of pumping volume, at present sucking rate
It is up to standard to be computed extraction by 25.822m3/min.
(2) before tunnel initating, using ordi-nary drilling machine construction coal bottom hole and spy top, hole is bottomed out, double lanes arrange 33 altogether
Hole (wherein bottom hole is 21, and bottoming out, visiting apical pore is 12).
2, even two group areas (East north wing adhesive tape/transportation roadway) is adopted
(1) 700 meters or so (perforation section) kms are even adopted in front of two groups of Easts north wing adhesive tape/transportation roadway to drill extraction 4
Month, 5 meters or so of whole pitch of holes, amount to 137.6 ten thousand side of pumping volume, sucking rate 5m3/min or so, is computed extraction and reaches at present
Mark.
(2) before tunnel initating, using ordi-nary drilling machine construction coal bottom hole and spy top, hole is bottomed out, double lanes arrange 39 altogether
Hole (wherein bottom hole is 27, and bottoming out, visiting apical pore is 12).
Drilling needs to consume manpower, power and time, has certain cost.If conceptual design is improper, will increase
Cost.Therefore, under the premise of guaranteeing quality and driving safety, punching quantity is reduced as far as possible.

Take drilling construction Optimized Measures front and back of the present invention comparison: 325 drillings of Shaoshi work altogether, about 32500 meters
The distance of drilling depth has saved a large amount of punching cost.
Assay and local outburst prevention work propose effect measure:
(1) region is evaluated according to 92 meters.Double lanes are total to design sample point 6, and coring hole is arranged in coal seam lower part and (utilizes
Coring bore detecting lower part whether there is cherry coal), control range is 15 meters of tunnel contour line, after gas bearing capacity is up to standard, and region permits
Perhaps 72 meters are tunneled.
(2) wind deslagging and coal seam gas-bearing capacity Quick testing instrument are tried out, after data comparison, select finding speed fast and
The accurate method of measurement result, to shorten the time of coring.
(3) working face prediction occur exceeded or section there are soft layering need to construct pressure relief vent when, pressure relief vent and pre- gaging hole
Can construct simultaneously and optimize pressure relief vent design, can either effectively shorten predicted time also safeguard measure take it is not excessive.
(4) for allowing to tunnel 29 meters after local prediction it when, need to meet head on construction 3 to surpass in tunnel after 10-12 meters of driving
Preceding inspecting hole, advanced inspecting hole length guarantee on the basis of remaining digging footage there are 10 meters it is advanced away from.
The features of the present invention: (1) reducing drilling number, propose effect effect to reach, and (2) reduce inspecting hole distance, guarantee lane
Road tunnels safely, and (3) increase horizontal river spacing, reduces production drilling depth, and (4) introduce advanced drill carriage, and saving is drilled and predicted time.
After the wing glue of this mine, transportation roadway promote and apply, hole count of drilling not only is saved, but also guarantees safety driving, and also
Improve the drilling depth of team's group driving.Region can be covered in all km drillings in coal mining area to be promoted.
