The mining method provided by the invention is suitable for the mining of underground metal loose and soft fragmental orebodies by adopting non-explosive technology to excavate column wells and filling the column wells to form artificial group-columns in order to replace artificial pillars, and has advantages of simple construction process, high construction efficiency, low production cost, high mining efficiency, and large production capacity of ore blocks and panels.

Description

Non-Blasting Excavation is reproduced artificial bundle pillar deep hole ore caving afterwards filling mining method
Technical field
The present invention relates to a kind of non-Blasting Excavation and reproduce artificial bundle pillar deep hole ore caving afterwards filling exploitation method, especially be applicable to the exploitation of underground metallic ore soft broken ore body.
Background technology
The soft broken metalliferous deposit is regarded as a kind of complicated uneasily mining orebody always, because the joint fissure of ore body is grown, ore deposit rock resistance to overturning is relatively poor, can allow exposed area little, and therefore many employing downdraft mode access back-filling methods carry out the back production of this type of ore body.And in traditional downdraft mode access back-filling method, the method that its artificial bar post is constructed still is to adopt down to construct to the route cemented-method, the work cycle of this method for constructing comprises driling explosion, ore removal, filling and protects top etc., after finishing a circulation, therefore change the back production of another layering again over to, exist complex process, safety condition is poor, operating efficiency is low, adopt and fill that cycle period is long, labour intensity is big, nugget production capacity is low and shortcoming such as mining cost height.Therefore, traditional artificial bar post mode of constructing is restricting the back production efficient of downdraft mode route mining codes, also has influence on the production capacity in whole panel.
Summary of the invention
Technical problem to be solved by this invention provides a kind of in the soft broken orebody mining, the efficient height of constructing, technology are simply, cost is lower and the stability of stope and bundle pillar is high, operating efficiency height, the non-Blasting Excavation that nugget production capacity is big reproduce artificial bundle pillar deep hole ore caving afterwards filling mining method.
In order to solve the problems of the technologies described above, non-Blasting Excavation provided by the invention is reproduced artificial bundle pillar deep hole ore caving afterwards filling mining method, in bar post ore body scope, excavate the post well of some by certain arranged mode with the raise boring machine drilling technology, after treating that the post well has excavated, put into reinforcing cage within it, reinforcing cage can be put in segmentation, adopt concrete to carry out filling then, form artificial bundle pillar with this, the mechanical property of bundle pillar satisfies the requirement of STOPE STABILITY, substitute artificial bar post, around the section of back production ore deposit, form a firm relatively restricted clearance.Use large diameter, deep borehole ore caving mode rooming, one-time filling goaf after scraper ore removal, ore removal finish.
Construct the upper level of artificial bar columnar region and the chamber that lower horizontal is distinguished digging drill chamber, replacing reaming cutter at needs, in rig work chamber, creep into guide hole downwards, the guide hole diameter is 0.25m, and guide hole is given a farfetched interpretation to the chamber of changing reaming cutter, removes the guide hole drill bit, be replaced with reaming bit, and reaming from bottom to top, finish the excavation of post well, the diameter of post well is 2.0m.
Each post well excavates according to the mutual arranged mode of 1-2-1, and the diameter of post well is 2.0m, and post well spacing is 1.0m; Behind post well of every excavation, reinforcing cage is placed in segmentation in the post well, and the length that reinforcing cage is every section is 2m, and diameter is 1.6m, and the coupled columns well carries out concrete filling; Carry out the excavation and the filling of next post well then, finish the construction of whole artificial bundle pillar.
Around the section of back production ore deposit, utilize the post group who manually constructs to form a firm relatively restricted clearance, the Drilling large resistancing line is following to large diameter, deep borehole in drilling chamber, adopts deep hole ore caving mode to carry out back production; The ore of a large amount of avalanches is transported by scraper by drawhole, realizes strengthening ore removal; Ore removal is put casting resin, bashing by the filling down-hole in the artificial roof pillar after finishing.
The invention has the beneficial effects as follows, adopt non-blasting technique excavation post well, and the packed column well forms artificial bundle pillar, utilize bundle pillar to substitute artificial bar post, the efficient height of constructing, technology are simply, cost is lower and the stability of stope and bundle pillar is high, the operating efficiency height, nugget production capacity is big, has solved that artificial bar post is constructed inefficiency and the difficult problem that influences panel production capacity.
