Abstract
The invention discloses a non-explosive mining method by excavation, artificial group-column reconstruction, long-hole caving and subsequent filling, comprising the following steps of: excavating a certain quantity of column wells in a certain arrangement mode within the scope of ore pillars by the raise-boring machine well-drilling technology; placing steel reinforcement cages into the column wells after the excavation of the column wells, followed by filling concrete to form artificial group-columns, whose mechanical properties meet the requirement of stope stability and which are used to replace artificial pillars so as to form a relative stable restricted space around the ore mining areas; stoping by the major diameter long-hole caving mode, moving ore out by a scraper, and filling the goaf at a time after moving ore out. 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
Technical field
The present invention relates to a kind of non-explosive excavation and reproduce artificial bundle pillar deep hole ore caving afterwards filling exploitation method, especially be applicable to the exploitation of underground metallic ore break and broken orebody.
Background technology
The soft broken metalliferous deposit is regarded as a kind of complicated uneasily mining orebody always, because the developmental joint fissure of ore body, ore deposit rock resistance to overturning is relatively poor, can allow exposed area little, and therefore the downdraft mode access back-filling methods that adopt carry out the back production of this type of ore body more.And in traditional downdraft mode access back-filling method, the method that its artificial bar post is constructed still is to construct to the route cemented-method under adopting, the work cycle of this method for constructing comprises driling explosion, ore removal, filling and protects top etc., after finishing a circulation, therefore change again the back production of another layering over to, exist complex process, safety condition is poor, operating efficiency is low, adopt and fill that cycle period is long, labour intensity is large, nugget production capacity is low and the shortcoming such as mining cost height.Therefore, traditional artificial bar post mode of constructing is restricting the back production efficient of downdraft mode Drift stoping method, 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 break and broken orebody exploitation, the efficient of constructing is high, technique is simple, cost is lower and the stability of stope and bundle pillar is high, operating efficiency is high, and the non-explosive excavation that nugget production capacity is large reproduces artificial bundle pillar deep hole ore caving afterwards filling mining method.
In order to solve the problems of the technologies described above, non-explosive excavation provided by the invention reproduces 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 the post well has excavated, put into reinforcing cage within it, reinforcing cage can be put in segmentation, then adopt concrete to carry out filling, 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 relatively firm restricted clearance.Use large diameter, deep borehole ore caving mode rooming, scraper ore removal, the complete rear one-time filling of ore removal goaf.
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 from bottom to top reaming, 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; Then carry out excavation and the filling of next post well, 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 relatively firm restricted clearance, the Drilling large resistancing line is lower 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 of constructing is high, technique is simple, cost is lower and the stability of stope and bundle pillar is high, operating efficiency is high, and nugget production capacity is large, has solved that artificial bar post is constructed inefficiency and the difficult problem that affects panel production capacity.
