Description
Technical field
This utility model relates to a kind of tunnel structure, in particular to the tunnel structure of a kind of colliery system.
Background technology
The exploiting field scope in one system tunnel, panel, C group coal north, east, Zhu Ji Dong ore deposit: north to F29(∠ 70 °, H=0～30m) and bright
Longshan tomography (inverse) (∠ 70 °, H > 1000m), south to Dong Yi great lane protection coal pillar, to the east of DF113 tomography (inverse ∠ 65 °～70 °, H
=0～10m), wide west to work and pit shaft protection coal pillar line.This paneling 13-1 and 11-2 coal seam, corresponding ground absolute altitude is+
22.3m～+24.0m.
General gas control mode selects 11-2 coal to exploit in advance as protective layer.The gas control in this coal seam of 11-2 coal divides
Being two kinds, one is that " simultaneously four lane " is arranged, i.e. utilizes base plate extraction lane to drill and screens crossheading driving, is aided with ground well drainage
The gas pressure relief of 13-1 coal；Two is that 11-2 coal " simultaneously three lane " is arranged, utilizes the Comprehensive Gas Control lane of 13-1 coal seam floor to screen
Crossheading tunnels, and while exploitation 11-2 coal key protective layer, utilizes Comprehensive Gas Control lane and ground drilling, forms " trend
Intercept about Shang Shuan lane, vertical upper and ground drilling intercept up and down " three-dimensional gas pumping pattern, it is achieved to 11-2 and 13-1 coal
Combined governance.In addition to 1111 (1) work surfaces use " simultaneously four lane " and arrange, remaining all uses " simultaneously three lane ".
When designing in tunnel, panel, general C group seam mining conventional arrangement.13-1 coal and 11-2 coal seam interlamellar spacing exist
About 65m～70m, according to group company C group coal mining experience, 13-1 and 11-2 coal generic hierarchical is arranged, is wherein exploited 11-2
5 tunnels, respectively 11-2 coal seam return airway, 11-2 coal seam floor sealing-tape machine lane, 11-2 coal seam floor track lane, 11-2 is arranged during coal
Coal seam floor spoil sealing-tape machine lane and 11-2 coal top board spoil sealing-tape machine lane；3 tunnels, respectively 13-1 are arranged during exploitation 13-1 coal
Coal return airway, 13-1 coal seam floor sealing-tape machine lane and 13-1 coal seam floor track lane.
Stope drift active workings with system tunnel connected mode are: crossheading is directly connected with coal seam return airway, and exploiting field rail system leads to
Crossing to carry and expect that inclined gallery are connected with crossheading, crossheading is connected with sealing-tape machine system by coal bunker (milling coal hole).
Along with mining area exploitation lower limit is the most downward, cost of winning is continuously increased, the renewal of auxiliary conveying equipments, above-mentioned layout
There are the following problems for mode: 1) C group coal mining need to arrange that 8 system tunnels, quantities and investment are the biggest, causes cost of winning
Higher, of poor benefits；2), in air return system is arranged in coal road, needs extraction borehole shielding driving of constructing before construction, affect exploiting field and throw
Produce the duration, strengthen investment, and coal road later maintenance quantities is big；3) in the protection coal pillar of system tunnel, crossheading is coal road, also needs
Extraction borehole to be constructed screens, and borehole engineering amount is big, and the construction period is long；4) little structure bend is many, does not utilize mine to assist
Transport serialization.
