Method.
Background technique
Coal mine is the mankind in the region of the mining area exploitation coal resources rich in coal, is generally divided into underground mine and outdoor coal
Mine.When coal seam is remote from earth's surface, it is typically chosen to underground and digs tunnel digging coal, this is underground mine.When coal seam is away from earth's surface
Distance it is close when, be typically chosen directly removing surface soil layer excavate coal, this is open coal mine.China's overwhelming majority coal mine category
In underground mine.Coal mine range includes the very big region of above and below ground and related facility.Coal mine is the mankind in digging rich in having
The proportional space excavated when the geological stratification of coal generally includes tunnel, well cave and face etc..Coal is most important solid
Fuel is one kind of kaustobilite.It is the plant in great numbers grown by certain geological epoch, in suitable geological environment
In, it is gradually accumulated into thick-layer, and be buried in water-bed or silt, is formed by very long geochronic geochronic natural incoalation
's.It is most with producing coal in the stratum in the Carboniferous Period, the Permian Period, Jurassic Period and the Tertiary Period in the world in Various Geolcgical Ages, it is important
Coal-forming age.The phosphorus content of coal is generally 46~97%, brown to black, has dim to metallic luster.According to coalification
The difference of degree, coal can be divided into peat, four class of lignite, bituminous coal and anthracite.
Probing is a kind of most direct hidden factors causing disaster exploration technology, it has, and precision is high, intuitive is strong, adaptive surface is wide
The advantages that, it is detected in structural exploration, old Exhausted area prospecting, leting speeper, gas pressure release, flame range detection and other hidden factors causing disasters

S4: leting speeper hole: the region 80m opens up dewatering orifice before meeting head on.
Preferably, the quantity of the release hole in the S1 is 5, single hole depth 30m, grouting amount: cement 30t, waterglass
8t。
Preferably, the slip casting hole number on the tunnel two sidewalls in the S2 is 100, the injected hole on the two sidewalls of tunnel
Be staggered in eight words, two laterally adjacent injected holes at a distance of 3000mm, two longitudinally adjacent injected holes at a distance of 1500mm,
Single hole depth 5m, grouting amount: cement 20t, waterglass 5t.
Preferably, rock plug is to be provided with upper injected hole of meeting head in the S2, and hole count is 10, single hole depth 10m, slip casting
Amount: cement 10t, waterglass 3t.
Preferably, the quantity of advance borehole is 10, single hole depth 60m in the S3, grouting amount: cement 150t, waterglass
30t。
Preferably, discharging water hole number 1 in the S4, hole depth 80m.
Compared with prior art, the beneficial effects of the present invention are: the present invention is dissipated tunnel by diversion pressure release, broken grouting
Water, water drenching import discharge pipe line, effectively improve tunnel looks；It effectively prevent meeting head on to have crack race by construction " rock plug "
Slurry, keeps slip casting effect more preferable；By front pre-grouting, rock fracture can be made effectively to be reinforced, within the scope of grout injection control
It can avoid the appearance of larger water burst in tunneling process, tunnel material properties of rock can be made to have good reinforcing, it is strong to increase country rock
Degree, it is ensured that roadway surrounding rock can be reinforced effectively, be filled to crack by the safety in work progress, and it is steady to increase country rock
It is qualitative, reduce water yield, it is ensured that construction safety.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention；
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
