Technical field
Coal cleaning field, more particularly to a kind of cleaning plant, cleaning side that coal is spread for shaft bottom are spread the present invention relates to shaft bottom
Method and layout method.
Background technology
It refers to, using vertical shaft skip lifting, well to be fallen into skip bucket loading and unloading or lifting process that coal is spread in coal master's vertical shaft bottom
The coal at bottom.And old-fashioned bend is used main vertical shaft hoisting uninstalling system in the past more, and spreading that coal is more, skip shaft spreads coal and accounts for mine daily output
3 ‰~the 5 ‰ of amount, and spread system clearly and coal is typically spread using Rabble mine winch cleaning, chamber mainly has main vertical shaft bottom funnel, spreads coal
Chamber, Rabble mine winch chamber and gole etc..Cleaning technology is:The coal and water in shaft bottom are fallen into by the conversion chute point under funnel
Not Jin Ru gole both sides slusher road, coal is loaded by mine car by rope traction slusher by Rabble mine winch；Black water passes through
Dehydration plate flows into gole, after precipitation outflow cleaning scattered coal chamber.When pit shaft water drenching is more, coal water is caused to mix, shape
Into coal slime, cleaning is difficult, and easily blocks buccal funnel under pit shaft.
In recent years, main Shaft Hoist Equipment and loading and unloading equipment have larger improvement, main vertical shaft bottom is spread coal amount big
It is big to reduce, spread coal amount is reduced to the mine daily output 1 ‰~less than 2 ‰；And new type of shaft structure is used shaft of vertical well more, plus
High-strength concrete and waterproof material application, pit shaft water drenching is greatly lowered, typically in 5m3/ below h, but
Existing coal Removal Technology of spreading still suffers from many problems.Such as：Existing coal Removal Technology of spreading needs to tunnel a tunnel again, with
Main shaft bottom is connected, and cleaning equipment is influenceed by black water in pit shaft, in most cases needs artificial assist process,
Cleaning efficiency is relatively low.
