A mineral well is well ventilated and safe
Section 1 is all the condition
1, gas
The provision of the basis coal mine safe rules distance Article 133s:" In a mineral well as long as have to discover a gas in a coal( rock) layer, the mineral's well is the gas mineral well." The coal mine scope outside of 416 numbers drill a hole,16 number coal seam CH4 contents amount to the 10.86 m3s/ t, therefore, this area also belong to the high 沼 spirit gas mineral well, passing to complexion mutually compose the instrument analysis, discover a little amount and heavy hydrocarbon air, past development hour the pole must notice and keep the coal seam 沼 from annoy the outstanding danger.
The chessboard well area 57 coal mines once have a gas explosion on March 6 in 1976, the reason is bad-ventilated, the clear fire illuminate, the clear fire fires a gun to cause, causing the coal dust explosion at the same time, resulting in important trouble that 7 people die.
2, coal dust:The mineral area coal seam dust explosion coefficient all above 10%, the flames length 10-700 mms, have sex of explosion, should value the dust palliative and put out the dust work in mine process.
3, coal of from 燃 :Each coal seam is in addition to the minority three and four classes not easily from ignition point, the most is in first, second classly easily from 燃 incline to class, so each coal seam of this area all belonged to easy rained the coal of adopt from the well to deposit to 6 months to all start take place to catch fire in the earth's surface from the burning coal, the 邻 area data manifestation,, especially rain after alter from the 燃 .
This mineral should adopt the aggressive measure in aftertime develop activity, prevent°froming the coal seam from the 燃 , particularly a heap of coal heap for put, even should adopt the enough measure.
4, a:This area did not discover a ground of abnormality, belonging to a ground of area with normal.
Section 2 mineral well airiness
A, well ventilated way and well ventilated system
1, well ventilated way
The well ventilated way of the mineral well for machine draw out type airiness.
3, well ventilated system
Expand to arrange according to this mineral well, make sure that well ventilated system of the mineral well is a central march past.Know well to see the diagram C1240-171-1,2.
Two, breeze well number, position and service time limit
Make use of the mineral well north at first fluently north well of industry, be used as the mineral well total to return to the breeze well, serve in the whole mineral well, the service time limit for the whole service time limit of mineral well.
Three, the digging work face and room airiness of 硐
The digging work face" U" a well ventilated system of adoption, for take to press well ventilated, the that digs into the work to face to adopt the bureau presses into the type well ventilated, well descend establish totally a digs into the set 2 dig into the noodles, adopting the type YBT-5.5 breeze machine to provide the breeze.
Well next the 硐 room is well ventilated to divide two, a 硐 room, go together with the breeze system independently such as the winch 硐 room adoption, another room of 硐 , if change electricity to wait to adopt the establish type or well ventilated system that merge the water pump house.
Four, the well descends the well ventilated facilities
The well ventilated network of this mineral well is simple, so well ventilated facilities and construct the thing less, in order to regulate the amount of breeze and prevent°from the romantic short circuit, establish the breeze door of the certain number and regulate the breeze door respectively in each breeze road only.The gearing of the breeze door establishes possibly in not affecting the conveyance of tunnel, moreover, for prevent°froming the well destroying the well ventilated and main under the gas explosion, at returned to inclined and tidy of breeze to install the flameproof door.
Five, the safety flees for life the path
Expand to arrange according to the mineral well, this mineral well establishes four safeties to export, namely main and vice- tidy tube, enter, return the tidy tube of breeze, all can be the well the safety export, well next once take place the strong trouble, the staff member can immediately withdraw the ground through these four exits, and under the well the mark has to avoid the disaster circuit marking obviously

The mine development activities in the future, should take active measures to prevent coal bed spontaneous combustion, especially the stowage Meizui should take adequate measures. 4, geothermal : the zone undiscovered geothermal anomaly, a normal geothermal zone
II ventilation
1, ventilation methods and ventilation
1, ventilation methods for mechanical ventilation shaft way out of ventilation. 3, the new ventilation system under the mine layout, the ventilation system to determine the breakdown ceremony. See Figure C1240-171-1, 2.
