Description
Technical field
The invention belongs to the coal mining apparatus field, relate in particular to a kind of coal on automation working face of low-seam shearer loader a complete set of equipment that is adapted to the complex geological condition thin seam mining.
Background technology
China's girdle aboundresources, widely distributed.The ratio of the shared coal gross reserves of girdle reserves is great, and only state-owned colliery girdle reserves proportion just accounts for 20% left and right, and local mine girdle reserves proportion is larger, and widely distributed, concentration of local.Because domestic many mines are not followed the science mining sequence, " eat fertilizer lose thin, adopt thick abandon thin ", high seam mining, cause the original occurrence status of girdle and the continuity covered on it in certain limit to suffer substantive destruction, so that the irretrievable problem of these resources is very serious too early.Establish the problem of the resource awareness of unexpected development and rational exploitation resource and should mention important schedule.New period national economy rapid growth, coal demand will continue to keep growing trend.Can predict, adopt the technical support coal production if only rely on existing combining, the colliery overall throughput must occur and descend within than short-term, mine life is accelerated to shorten, and the confession ability of China's main body energy will suffer the consequence of severe challenge and destruction.
Because thin seam mining exists poor working environment, required workman is many, labor strength is large, coal production is low, deficiency in economic performance, production security is poor, ventilate not smooth, methane accumulation, the problems such as the gas management difficulty is large, above-mentioned variety of problems make the thin seam mining in a lot of mining areas be in the stagnation situation that even falls back, and more cause the output of girdle only to account for 7.3% of gross reserves, well below the shared ratio of reserves, and this ratio also has further downward trend.But the exploitation of girdle is the important indicator that affects coal recovery rate always, and improving the rate of extraction is also the emphasis that each coal mining enterprise chases.
So safety, production technique high-yield and high-efficiency of exploitation girdle and equipment are imperative, are reasonable reclaiming coal resources, ensure that the colliery economic benefit is stable, the only way of sustainable development; Only have application of thin coal seam safety and high efficiency technical equipment, could ensure that the ratio of adopting of joining thin, high seam is complementary with the actual ratio of depositing of composing.
In recent years, be Speeding up development girdle resource, the problems such as work under bad environment, poor stability and the operating space that exists in raising thin seam mining process is limited, each large Mining Group and coal machine are made enterprise and have been strengthened the research of putting face at girdle automation a complete set of equipment, and obtain some application achievements, realized work plane middle part move the functions such as frame, auto spraying, pushing and sliding with machine, and camera is installed on coal-winning machine or hydraulic support has been realized video monitoring to work plane.But, the girdle flitting work plane automation a complete set of equipment of development has only been realized the automated mining in the middle part of work plane both at home and abroad at present, and all need cut sth. askew feed and cut Triangle Coal, clear coal of manual intervention in the work plane two ends, can't realize unmanned or few people's exploitation of work plane.
