Description
Technical field
The present invention relates to a kind of coal excavation apparatus, and in particular to a kind of flitting for ultra-thin coal seam.
Background technique
Coal is the main body energy in China, and coal industry is the important foundation production of relationship energy security and lifelines of the national economy
Industry.China is incorporated into the coal seam thickness less than 1.3m as girdle, and the coal seam that thickness is less than 0.8m belongs to ultra-thin coal seam.Study of Thin
And ultra-thin coal seam high efficient mining technology has important practical significance.China's girdle resource distribution is extensive, the coal seam 1.3m or less
Recoverable reserves accounts for about the 20% of whole recoverable reserves.It is very big in some provinces, area's girdle reserves specific gravity, if Sichuan Province accounts for 60%,
Shandong Province accounts for 54%, and Heilongjiang Province accounts for 51%, and Guizhou Province accounts for 37%.Especially in southern area, some province girdles account for only
50% or more, and girdle distribution is wide, and coal quality is good.It is thin compared with middle thick and high seam but since its working seam thickness is thin
Coal seam mechanical mining is there is working under hard conditions, and equipment is mobile difficult, the geological structures such as Coal Seam Thickness Change, tomography, to thin
Coal seam equipment production performance influences big and input-output ratio height, economic benefit not as good as the specific questions such as thickness and medium-thickness seam, makes
It is relatively slow at girdle mechanical mining technology development speed.
In addition, to some thin, high seams and the coal mine deposited makes the middle thickness of its underpart since thin seam mining speed is slow
Coal seam cannot exploit in time for a long time, so that normally taking over for working face is influenced, and some can only just be forced to lose some bog-head coals
Layer resource.With in large quantities of coal mines, the resource exploitation of high seam it is relatively more so that resource is fewer and fewer, so girdle is opened
It adopts and has been included in schedule.Therefore, developing is suitble to the low seam mining machinery of the practical national conditions in China to mention to adapt to different coal bed textures
The working efficiency that high girdle is mined is the task of top priority.Medium-thickness seam is usually preferentially exploited at operation initial stage in past, each mining area,
1.3 meters of coal seams below are all abandoned, and a large amount of precious resources are wasted, and shorten the viability of mine, constrain entire coal
The coordinated development of charcoal industry.Coal is non-renewable resources, continuous extension of many coal mines with the exploitation time limit, medium-thickness seam money
Source is close to exhaustion, for the Yanchang Area length of service, it has to start back production thin layer coal.In this case, in order to treasure
Existing coal resources liberate coal resources by every possible means, improve coal recovery rate to the maximum extent.
China's low seam mining machinery passes through development in more than 40 years, and technology has become mature, but there are also several outstanding problems: first
Since the volume and weight of coalcutter is excessive, the installation and displacement in working face are all very difficult, and cost still compares
High (10,000,000 yuan or so) can be only applied to large and medium-sized coal mine and the relatively good mining area of seam construction condition, and mining height is general
1 meter or more can only be adapted to, 0.8 meter of thin layer coalcutter below is still blank at home at present.Therefore middle and small scale coal mine is anxious
Need a kind of compact and flexible, economic and practical thin layer and thin layer coalcutter.Since small-size coal mine accounts for the 2/3 of whole coal mine quantity,
Its radix is huge, thus pent-up demand amount is very considerable, and in addition coalcutter is typically all and works continuously within 24 hours in underground, and
Working environment is poor, and the service life of critical component is low, and frequency of maintenance is high, and maintenance cost is high.
