The invention relates to a method of mining coal at large mine-layer thickness, characterized in that: two separated mining devices are used for mining the coal and respectively separatedly operate along the vertical direction and the horizontal direction and one own transporter is respectively assigned for each mining device.
Description
Technical field
The present invention relates to a kind of in the situation that the method for large seam thickness mine coal and a kind of force piece of using in this method.
Background technology
The current known largest equipment that is used for the exploitation of cutting is suitable for the seam thickness of the highest 6m of being approximately.This restriction is that the use due to operational roll-type charger (Walzenlader) forms.Although in principle, force piece may be designed for higher seam thickness.Yet the transportation of this force piece and manipulation have produced huge problem.
Summary of the invention
The object of the invention is to, propose a kind of method and a kind of device to be used for mine coal, utilizing the method and install can be in the situation that large seam thickness be realized effectively exploitation.
This purpose by so a kind of in the situation that the method for large seam thickness mine coal realize, it is characterized in that, described exploitation realizes by the mining equipment of two separation, the vertically and flatly each interval operation of turning up the soil of described mining equipment; For each mining equipment is assigned self a conveyer.
Utilization is according to exploitation method of the present invention, and step was implemented by two mining equipment, for example roll-type charger (Walzenlader) in two stages, and wherein these two mining equipment are each other approximately moved with level vertically overlappingly at interval.By this method, namely use two steerable mining equipment independently of one another, and wherein for each mining equipment is assigned self a conveyer, can make thus a large amount of coals broken and transport simultaneously.
Favourable embodiment of the present invention is described in manual, accompanying drawing and dependent claims.
The embodiment favourable according to first, the first mining equipment can (amHangenden) be moved on top board, and the second mining equipment can (am Liegenden) operation on base plate.Guaranteed by this way, namely when this mining equipment operation, mining equipment also has enough supportings by the coal of also not exploited on top board.
If if the first mining equipment is moved on the thickness more than half seam thickness in operation and/or the second mining equipment on the thickness of fewer than half seam thickness, this can be favourable.If for example the first mining equipment is arranged in above the second mining equipment, the size of this first mining equipment can design approximately littlely, thereby makes the top part of working face equipment (Strebanlage) can be designed to have less weight.
If exploitation method is implemented so in addition, i.e. the exploitation of coal is looked into stairstepping and is carried out on the direction perpendicular to tunneling direction, and this can be favourable.By this way, the top part of working face equipment can be supported between the productive life on ladder below being positioned at by the material of also not exploited is formed.
Have at least two stepping mechanisms (Schreitwerke) of arranging overlappingly vertically according to force piece of the present invention, that use in the method for aforementioned type, stepping mechanism is arranged in two planes that stack vertically, and stepping mechanism flatly stagger each other especially (versetzt) arrange.Thus, the top part of force piece can irrespectively be removed and install with the bottom part.Force piece can have four pillars altogether, wherein two pillars can be supported on the pedestal of (am Liegenden) on base plate, and two pillars can be supported on another and are arranged on pedestal on the ladder that coal cutting roadway wall (Kohlenstoss) locates.In this embodiment, force piece has at least two pillars, and the point of going to the bottom of pillar (Fu β punkt) is arranged in two planes that stack vertically, and wherein put and flatly is staggeredly arranged each other especially at the end.
The embodiment favourable according to another, force piece has top bottom-disc, and it is suspended on the upper extreme point of lower supporting rod.By this way, lower supporting rod (its end point be placed in low bottom-disc place) is used as the support for top bottom-disc, and it has carried this one or more upper supporting columns, and this upper supporting column roof supporting.
Can produce thus stable layout, namely the pillar of the bottom part of pillar, for example force piece tilts at direction of extraction, and that pillar of the top part of another pillar, for example force piece is in reverse to direction of extraction.
In order to ensure the top part of removing rapidly and uncomplicatedly with installation work face support, if force piece has top bottom-disc, and this top bottom-disc is connected with the top bottom-disc of adjacent support by propelling hydraulic cylinder, and this can be favourable.Equally also can advantageously namely be provided with the control device for force piece at this, can adjust the step pitch for the stroke of this propelling hydraulic cylinder in control device, wherein the range of propelling hydraulic cylinder is at least the twice of step pitch.Make by this way the step sequence that will implement in the situation that the work plane feeding is transformable.
The embodiment favourable according to another can be furnished with vertical base plate on the bottom surface of the top bottom-disc of force piece, by means of this base plate, top bottom-disc is supported extraly, and its method is that base plate is resisted against the coal cutting roadway wall.At this, base plate can or only be articulated in the chassis, or can regulate by regulating cylinder in order to realize better controllability.
Be approximately 8 to 10m at the bottom base of force piece and the distance between top cover (Kappe), thereby can realize exploiting large seam thickness.
