Description
Technical field
The present invention relates to the underground mining design for scheme, particularly a kind of sublevel fill-mining method.
Background technology
Sublevel caving method without sill pillar is a kind of mining methods that present underground mine is most widely used.This method is compared with other mining methods, have simple in structure, flexibility is big, does not need pillar, and the mining preparation work amount is little, process for stoping is simple, rock drilling voluntarily, carrier loader efficiently easy to use, work such as rock drilling, ore caving and ore removal are all carried out in stope drift active workings, and safety condition is good, the labor productivity height, the outstanding advantage of the big grade of ability.But sublevel caving method without sill pillar also exists simultaneously and covers ore drawing under the rock, and loss late, the rate of dilution are higher, draw control strictness, operation in dead face, critical defects such as ventilation condition difference.And the most basic applicable elements of this method is that the face of land allows avalanche.When the face of land did not allow avalanche, sublevel caving method without sill pillar just can not use, and its outstanding advantage also just has no way of bringing into play.
Open-stope method under given conditions, can stop the face of land to subside.But, need stay suitable ore pillar underground, become permanent loss.If the goaf has comprehensive utilization value, this permanent loss perhaps also is worthy of consideration.Otherwise filling is carried out in the reply goaf, to eliminate safe hidden trouble.And when bashing, the reply ore pillar reclaims.
In order to reclaim ore pillar, must carry out consolidated fill to mineral building.Cemented fill must have enough intensity.Otherwise the safety that reclaims ore pillar work just can not get guaranteeing.Consolidated fill not only needs suitable fund input, and needs the long time to drop into.Because cemented fill needs the time maintenance.The top that connects of obturation is to be difficult to realize that particularly cemented fill will shrink and sedimentation in solidification process.After cemented fill was shunk, it must be impossible connecing the top.As seen, consolidated fill cost height, effect is unsatisfactory.
Dry stowing is a kind of original filling method, it is believed that this filling method labour intensity is big, pack effectiveness is low, of poor quality.Thereby dry filling method is abandoned by people.Needing the underground mine of filling, generally do not considering dry stowing, and more hanker after hydraulic fill or consolidated fill.Yet, to compare with hydraulic fill and consolidated fill, the dry stowing facility is simple, and is with low cost, after filling operation is finished, can carry out mining activity immediately, do not need to wait for the dehydration of hydraulic fill or the maintenance of consolidated fill.
Summary of the invention
For solving the problems referred to above that prior art exists, the objective of the invention is at need filling, ore and country rock medium above firm, tilt to the thick above or extremely thick ore body of gentle dip in the high-dipping, a kind of safe, efficient, advantage that ability is big that had both had sublevel caving method without sill pillar proposed, can effectively avoid the face of land of sublevel caving method without sill pillar to subside again, the shortcoming of loss late height, rate of dilution height, ventilation condition difference, the technology bottom-column-free sectional filling mining method simple, with low cost that also has dry filling method simultaneously.
