Abstract
The invention discloses a method for sectionally driving a raise. The difference of the method is as follows: a long raise is divided into a plurality of sections of short raises for driving, upper and lower sections of stope communication passages are mutually staggered in the horizontal position and are arranged at both sides of the raise respectively, the stoping of a first section of ore body can be performed after the raise is communicated with the second section of stope communication passage, the driving of a third section of lane is performed after the first section of mining, the raise is upward driven from the second section and is communicated with a third section of stope communication passage, the construction of other sections of raises is performed according to the method until the uppermost section is communicated with upper and middle sections of ventilating laneway. Therefore, the method has good ventilation effect, safe operating environment, small labor intensity and high driving efficiency, greatly reduces production cost, and is particularly suitable for raise driving in high and middle sections of gently inclined medium thick ore bodies.
Description
Technical field:
The present invention relates to a kind of method of tunneling courtyard, the method for sublevel drive courtyard in particularly a kind of high stage casing, the gently inclined medium thick orebody.
Background technology:
At present both at home and abroad when the courtyard of the high stage casing of driving, main adopt suspended bulkhead raising method, climb pot process, deep hole blasting method and machinery and creep into method, wherein suspended bulkhead raising method, deep hole blasting method only adapt to the inclined orebody more than 60 °, but climb pot process and machinery and creep into the slow courtyard of method appropriate angle, but these two kinds of methods all have equipment investment big, the maintenance of equipment complexity, the shortcoming of cost height and driving preparatory construction maximum, middle-size and small-size mine is difficult to adopt.
Summary of the invention:
Purpose of the present invention will provide a kind of ventilation effect good exactly, operating environment safety, and labour intensity is little, drivage efficiency height, a kind of sublevel drive courtyard method that reduces production costs.
The object of the present invention is achieved like this:
A kind of sublevel drive courtyard method is characterized in that may further comprise the steps:
1, suitable position driving courtyard as the initial scope of freedom of stope connecting taxiway, prospecting drift and the first floor back production of first layering, is chosen, to the two-section level in the vertical ore body driving tunnel that undercuts from a segmentation lane.
2, driving two-section stope connecting taxiway, the stope connecting taxiway of two segmentations staggers on horizontal level mutually up and down, is arranged in the both sides of courtyard, and the stope connecting taxiway of courtyard and two-section just can carry out the back production of a segmentation ore body after connecting.
3, behind one fen section mining, carry out three segmentation lanes driving, the stope connecting taxiway that drives up courtyard and three segmentations from two-section connects, and other each segmentation sky well construction all carries out according to above method, connects up to the airway in a segmentation of going up most and a last stage casing.
The present invention compared with prior art has following advantage:
Since adopted above step, thereby ventilation effect is good, operating environment safety, labour intensity is little, and the drivage efficiency height greatly reduces cost of production.
The specific embodiment:
1, suitable position driving courtyard as the initial scope of freedom of stope connecting taxiway, prospecting drift and the first floor back production of first layering, is chosen, to the two-section level in the vertical ore body driving tunnel that undercuts from a segmentation lane.
2, driving two-section stope connecting taxiway, the stope connecting taxiway of two segmentations staggers on horizontal level mutually up and down, is arranged in the both sides of courtyard, and the stope connecting taxiway of courtyard and two-section just can carry out the back production of a segmentation ore body after connecting.
3, behind one fen section mining, carry out three segmentation lanes driving, the stope connecting taxiway that drives up courtyard and three segmentations from two-section connects, and other each segmentation sky well construction all carries out according to above method, connects up to the airway in a segmentation of going up most and a last stage casing.
