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 that present underground mine is used the most a kind of mining methods.This method is compared with other mining methods, has simple in structurely, and flexibility is big; Do not need pillar, the mining preparation work amount is little, and 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; Labor productivity is high, 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, and draw control is strict, 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.It is thus clear that the consolidated fill cost is high, 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, and filling operation can be carried out mining activity after accomplishing immediately, need not wait for the dehydration of hydraulic fill or the maintenance of consolidated fill.
