Abstract
The invention discloses a sill pillar stoping process. The difference of the sill pillar stoping process lies in that the sill pillar recovery process comprises the steps: (1) the arrangement of a pre-grouting drilling hole; (2) the pre-grouting; (3) the roof-contact filling in stope; and (4) the sill pillar stoping. Therefore, the process is simple, safe and highly-efficient, has low cost and high stoping rate, and is particularly suitable for the sill pillar stoping of mines.
Description
Technical field:
The present invention relates to a kind of process for stoping, particularly a kind of bottom column stope process.
Background technology:
Bottom column stope will just can carry out after next horizontal ore body has been adopted, open-assembly time generally reaches the several years, and owing to be subjected to process explosion power destructions such as haulage drift driving and mineral building back production, phenomenons such as roof fall, landslide very easily appear in reason such as pressure in the exploitation process with bearing, for both not adopting consolidated fill, do not have the concrete tailing-filled mining codes at the false end again, the bottom column stope difficulty is very big, and a lot of mines for the sake of security, can only abandon foundation and reclaim, cause resources loss.
Summary of the invention:
Purpose of the present invention will provide a kind of technology simple, safe and efficient exactly, and cost is low, the bottom column stope process that the rate of extraction is high.
The object of the present invention is achieved like this, and a kind of bottom column stope process is characterized in that may further comprise the steps:
(1) arrange pre-inlet well: when the stope of next horizontal segment is adopted to the distance haulage level 0.3-0.7 rice left and right sides, stop back production, utilize the YGZ-90 rig vertically to creep into then, penetrate ore body and surpass tailing-filled, the net degree is 1.0 * 1.0m
2To 1.5 * 1.5m
2
(2) carry out pre-slip casting: adopt cement grout, use high-pressure injection pump slip casting, the high-strength PVC pipe is a feed pipe for mortar, seamless steel pipe is a Grouting Pipe, carry out pre-slip casting, leak, use stopper as stop grouting plug at the injected hole collar extension for preventing slurries, clog with cloth near reaching Grouting Pipe on every side, after extracting Grouting Pipe out, immediately with cloth just the stopple on the stopper live, make tailings and slurries formation solid, and be full of the interior crack of foundation ore, make the glued one-tenth of ore whole.
(3) adopt the poplar top tight filling: after pre-slip casting finishes, stope is carried out top tight filling, filling should be carried out several times, and it is closely knit to guarantee that filling connects the top, for bottom column stope is laid good basis.
(4) bottom column stope: according to the thickness of foundation, divide and adopt the route type back production two～three times, first floor adopts mining advancing, for the ore deposit that falls forms enough spaces, retrusive, the safety of assurance personnel and equipment are adopted in the later ore deposit that falls, fall the ore deposit to apart from 0.5 meter in tailings face the time, finish bottom column stope.
The present invention compared with prior art has following advantage:
Owing to adopted following steps: (1) arranges pre-inlet well, and (2) carry out pre-slip casting, and (3) adopt the poplar top tight filling, (4) bottom column stope, thereby technology is simple, safe and efficient, cost is low, rate of extraction height.
The specific embodiment:
Embodiment 1:

2
(2) carry out pre-slip casting: adopt cement grout, use high-pressure injection pump slip casting, the high-strength PVC pipe is a feed pipe for mortar, seamless steel pipe is a Grouting Pipe, carry out pre-slip casting, leak, use stopper as stop grouting plug at the injected hole collar extension for preventing slurries, clog with cloth near reaching Grouting Pipe on every side, after extracting Grouting Pipe out, immediately with cloth just the stopple on the stopper live, make tailings and slurries formation solid, and be full of the interior crack of foundation ore, make the glued one-tenth of ore whole.
(3) adopt the poplar top tight filling: after pre-slip casting finishes, stope is carried out top tight filling, filling should be carried out several times, and it is closely knit to guarantee that filling connects the top, for bottom column stope is laid good basis.
(4) bottom column stope: according to the thickness of foundation, divide and adopt the route type back production two～three times, first floor adopts mining advancing, for the ore deposit that falls forms enough spaces, retrusive, the safety of assurance personnel and equipment are adopted in the later ore deposit that falls, fall the ore deposit to apart from 0.5 meter in tailings face the time, finish bottom column stope.
Embodiment 2:
(1) arrange pre-inlet well: when the stope of next horizontal segment is adopted to 0.5 meter left and right sides of distance haulage level, stop back production, utilize the YGZ-90 rig vertically to creep into then, penetrate ore body and surpass tailing-filled, the net degree is 1.5 * 1.5m
2
(2) carry out pre-slip casting: adopt cement grout, use high-pressure injection pump slip casting, the high-strength PVC pipe is a feed pipe for mortar, seamless steel pipe is a Grouting Pipe, carry out pre-slip casting, leak, use stopper as stop grouting plug at the injected hole collar extension for preventing slurries, clog with cloth near reaching Grouting Pipe on every side, after extracting Grouting Pipe out, immediately with cloth just the stopple on the stopper live, make tailings and slurries formation solid, and be full of the interior crack of foundation ore, make the glued one-tenth of ore whole.
(3) adopt the poplar top tight filling: after pre-slip casting finishes, stope is carried out top tight filling, filling should be carried out several times, and it is closely knit to guarantee that filling connects the top, for bottom column stope is laid good basis.
(4) bottom column stope: according to the thickness of foundation, divide and adopt the route type back production two～three times, first floor adopts mining advancing, for the ore deposit that falls forms enough spaces, retrusive, the safety of assurance personnel and equipment are adopted in the later ore deposit that falls, fall the ore deposit to apart from 0.5 meter left and right sides of tailings face the time, finish bottom column stope.
