Description
Technical field
The utility model relates to support apparatus under a kind of coal mine, is specially a kind of suspended bar timber of automatic moving type that is applicable to coal-face two lane advance supports.
Background technology
According to " safety regulations in coal mine " regulation, in all emergency exits of coal-face and junction, the tunnel 20m scope, must add strong supporting; Head-room in the comprehensive mechanical coal mining work plane, this scope must not be lower than 1.8m.Be to take to add in advance strong supporting in the coal-face two crossheading 20m scopes.
Fully-mechanized mining working faces end head is the intersection of work plane and stope drift active workings.The termination district is the interface point that fells and transports equipment, and this place's apparatus arrangement is intensive, and is the throat of pedestrian, ventilation, haul and defeated coal, and the quality of termination management and supporting is that can the decision work plane run well, the key of work plane safe coefficient.Thereby, improve the supporting situation of fully-mechanized mining working faces end head, realize the mechanization and the automation of fully-mechanized mining working faces end head operation, to improving mine productivity ratio and ensureing that mine safety is significant.
Traditional coal-face two crossheading advance supports mainly carry out supporting with hydraulic prop complexed metal articulated roof beam, confirm supporting parameter according to drift section and roof pressure situation, to guarantee the unimpeded of emergency exit.But special geologic condition with face face when exploitation, the limitation that hydraulic prop coordination hinge back timber carries out advance support shows gradually, mainly contains the following aspects:
(1) supporting intensity is low does not reach supporting intensity for the big coal seam of roof pressure, is prone to cause the work plane emergency exit to crush; It is many that individual prop bores the end, returns that to remove the intensive place, top of cutting of difficulty, particularly work plane rear portion especially true; Promptly increase labour intensity, be unfavorable for safety in production again.
(2) support speed is slow because the speed of removing that installs and return of hydraulic prop, back timber is difficult to increase substantially, and the restriction face propulsion speed is difficult to realize high-yield and high-efficiency
(3) labour intensity is big owing to install, return and remove individual prop and back timber is frequent, and all adopts manpower, causes the working face extraction user of service many, and labour intensity is big.
(4) cost is high, and poor stability is reason such as big or operation because of roof pressure, pillar, and the damage of pillar footwear is bigger, increases the cost expenditure, and complex procedures, and manually-operated is many, and the probability that causes the accident is bigger.Some pressure are big, the area of soft top board, and the metal roof bar recovery difficult is big, also need do log hut, and waste of material is serious.
Carry out the limitation of advance support to hydraulic prop complexed metal articulated roof beam,
Design that a kind of mechanical property is good, supporting capacity is high, install and tear open and move the leading extraordinary excavation support of stope easily.It has been a urgent problem.
