Description
Technical field
The present invention relates to a kind of coal mine underground sumps to dig clearly process and its equipment, belongs to coal mine underground sump and digs work clearly
Skill technical field.
Background technology
Mine water disaster is one of four big disasters of coal production, and shaft sump is to prevent mine water disaster, ensure that coal mine is pacified
The critical facility produced entirely.Dibhole digging problem is always to perplex a great problem of Safety of Coal Mine Production, in recent years, with adopting depth
Increase, inflow rate of mine water increase, the frequency of dibhole digging is higher and higher, and the threat degree brought to mine is increasing, such as
What reduces the frequency of dibhole digging, shortens and disposably dig the time clearly, improve the quality dug clearly, is the problem that a needs solve.
At present, coal mine underground sump digs clearly process and its equipment is mainly the following：
(1) artificial spade digs clearly method, loading machine digs clearly method, main insufficient：Labor intensity is big, working efficiency is low, digs clearly
Frequency height, the time length dug clearly, coal slime are in transportational process to the seriously polluted of environment.
(2) scrapper conveyor digs clearly method, bucket machine digs clearly method, main insufficient：Transport mine car leakage is serious, working efficiency is low, clear
The frequency height of digging, the time length dug clearly, coal slime are in transportational process to the seriously polluted of environment.
(3) utility model patent of Patent No. 200420092004.9《Water position slurry clearing and dugging machine》, authorized announcement date
On November 2nd, 2005；The utility model patent of Patent No. 200920163415.5《A kind of clear digging conveyer》, authorized announcement date
