Background technique
Coal mine refers to the place rich in coal resources, is commonly also referred to produce coal using subsurface excavation or openwork mode
Factory.Coal mine is the important energy source in China, is also important the raw material of industry.China's coal-mine rich reserves, coal mining
It is the important industry in China.It when coal seam is remote from earth's surface, is typically chosen to underground and digs tunnel digging coal, this is well work coal
Mine.When distance of the coal seam away from earth's surface is close, it is typically chosen directly removing surface soil layer and excavates coal, this is open coal mine.In
State's overwhelming majority coal mine belongs to underground mine.A large amount of tunnel can be generated when excavating coal mine, these tunnels are due to base layer support object
It is mined, lacks necessary support, be easy to happen avalanche event, it is therefore desirable to which the artificial support equipment that is laid with is supported.Tradition
Support equipment mainly plank is used to support, since the anti-pressure ability of plank is limited, and be inconvenient to adjust support degree, therefore
It is still easy to happen landslide event, with the development of economy, present coal mine is mostly used steel support frame, and majority is all one by one
It links together, it is often pretty troublesome in terms of installation and removal, and the support frame in mine hole is only only on mine hole both sides, for
Support at the top of mine hole will cause certain careless omission, in the case where mine hole needs long working, it is possible that avalanche
Phenomenon.Another aspect steel strength is high, but steel are easy to happen brittle fracture when great changes will take place suddenly when its stress, so
When avalanche occurs for coal mine, the stress of steel bracket increases suddenly, is easy for that brittle break occurs in the biggish place of some stress.
