Description
Technical field
The present invention relates to mining boxhole technical field, more particularly, to a kind of boxhole structure and its remodeling method.
Background technique
The production process of ore-rock: stope → scraper → stope box → mine car → discharge point → drop shaft → crude ore bin → slips
Mouth → vibration ore dumping machine → crusher → finished product ore storage bin → dress barrow band → measuring hoper → skip bucket → earth's surface ore storage bin → choosing
Factory ....Mine engineering has determined that its production scale in the project decision phase, all development engineerings thereafter all produce rule with it
Mould matches.Boxhole is that the throat of drop shaft positioned at the lower part of drop shaft is the component part of crucial importance of drop shaft, the production in mine
Ability unloads mine ability depending on boxhole, is fully able to meet up to production needs by the mine ability of unloading of the boxhole of production scale design.
During actual production operation, the influence of product price, performance assessment criteria etc. various aspects factor, bargh's meeting are suffered from
Promote production capacity.Production capacity, which is promoted, to be needed to carry out upgrading to these restraining factors by the restriction of existing engineering.In crowd
In more restraining factors, restriction most serious that boxhole promotes mine production capacity, also most critical.
Existing boxhole is designed as reinforced concrete structure, and the operation intensity in upgrading is high, long in time limit, cost
Height, and it is big to mining production Influence to operation.In addition, armored concrete boxhole can also restrict blocking thing when ore storage bin blocks
Therefore treatment effeciency and processing cost.
The bottom of boxhole structure is arranged in integral into the similar hollow bucking ladder structure stood upside down, ore discharging port in existing boxhole structure
Portion, it is Cheng Shuiping, vertical or skewed.According to drop shaft size, device structure and parameter, poured using armored concrete,
Simultaneously according to installation equipment needs, the pre-buried equipment mounting foot bolt or pre-buried in ore discharging port surrounding reinforced concrete structure
Welding steel.Boxhole wall inner surface and ore discharging port surrounding are equipped with wear-resistant liner, to prevent ore impact wear.
Once existing armored concrete boxhole structure pouring molding is promoted in later period mine production capacity, system upgrade transformation
When, reinforced concrete structure is not easy to be transformed, and generally requires to cut, and the ore discharging port after cutting will also result in the installation of new wear-resistant liner
Fixation is extremely difficult, and wear-resistant liner installation quality is difficult to ensure, labor operation intensity when transformation is high, long in time limit, at high cost, and
Mining production is influenced big.
