Description
Technical field
The utility model relates to a kind of anchoring forecasting and warning anchor rod system being specially adapted for the dangerous tunnel of coal and gas prominent of underground coal exploitation.
Background technology
For a long time, coal and gas prominent is one of topmost disaster in colliery, and great majority occur in tunnel.Such as: recent (on November 24th, 2014), at exploiting field 1135, the west of a river, ore deposit, Lupanshui City Xiangshui County of Guizhou Province driving face, a coal and gas prominent accident occurs, and causes 20 people wrecked, loses huge, had a strong impact on coal production reputation socially.In general, coal and gas prominent accident has the features such as sudden, instantaneity and heavy damage when occurring, before generation, omen performance is not obvious, during generation, coal rock layer sprays at a high speed the working space of scene under the effect of high methane pressure, with strong motion, destroy support, bury the significant incentive phenomenons such as mining equipment, directly the life security of threat coal mining staff and property safety.Therefore, the accuracy how more effectively improving coal and non-coal prediction is the key technology of mine safety.
In highly gassy mine recovery process, prevention Coal gas outburst is for the corresponding effective measures of this accident to strengthening supporting.Bolt support is widely used in colliery tunnel support because its supporting effect is good, cheap, and especially resin anchor is more applied by emphasis.Resin anchor serves as excellent cementing agent because of its resin anchoring agent at anchor rod anchored end, anchor rod anchored end is combined closely firm with coal and rock, and then ensure that anchor pole integer support performance.But; Anchor Agent has certain mobility; during rockbolt installation; usually there will be along screw thread overflow or Anchor Agent can not fully with rock stratum and the phenomenon such as anchor rod body contacts; greatly reduce the anchoring property of anchor pole; thus cause the supporting effect of anchor pole poor, there is the phenomenon that coal and rock and anchor rod body are synchronized with the movement, effectively can not control the distortion of coal and rock.Like this, under the effect of high methane pressure, the anchor pole of inefficacy easily and coal and non-coal spray simultaneously, cause serious accident.
Utility model content
In order to solve, high methane roadway deformation is large, distortion danger classes cannot show in advance, and anchored end Anchor Agent too overflows and affects the technical problem of anchoring strength, a kind of anchoring forecasting and warning anchor rod system for the dangerous tunnel of coal and gas prominent that the utility model provides a kind of structure simple, esy to use, safe and reliable.
The utility model is achieved by the following technical solution: a kind of anchoring forecasting and warning anchor rod system for the dangerous tunnel of coal and gas prominent, comprise backing plate, pointer, wire rope, the body of rod, interior bar, anchored end, described backing plate has circular port also to be passed through for wire rope with the affixed body of rod, backing plate has pointer groove, in pointer groove, pointer is installed, pointer groove has rule on one side, described pointer groove one end and circular port have linked hole to be passed through for wire rope, described wire rope is by the corresponding concatenation pointer in linked hole one end, bar in other end correspondence connects, the described body of rod is hollow lever, interior bar can be inserted in inside, end has for the outstanding aperture of compressible pellet, described interior bar is hollow lever, one end connecting steel wire ropes, length of cable is provided with determines the compressible pellet of intensity, the other end is provided with compressible pellet, corresponding connection anchored end, the anchored end other end is carved with external screw thread.
The utility model can also realize by following technical solution further.
Mechanical speed clock and watch are installed above described backing plate, mechanical speed clock and watch and backing plate front are left space and are passed through for pointer, described mechanical speed clock and watch are miniature speedometer, the tooth bar having speedometer exposed in the space in speedometer and backing plate front, finger slips is relied on to drive racks turn, rack drives speedometer pointer rotates, and after speed reaches certain value, stroke can be beaten.
Described pointer groove is opened in the diagonal of backing plate.
The end of described interior bar is provided with can uphold pawl, scalable disk is provided with in the middle part of described anchored end, described upheld pawl end is bending shell fragment, described scalable disk original state is recessed in the middle part of anchored end, after the anchoring stomidium that bending shell fragment is deeply corresponding, scalable disk can be pushed open along body of rod radial direction under external pressure effect, can open for diameter is greater than the disk of anchored end.
The beneficial effects of the utility model are:
One, for the tunnel with coal and gas prominent danger, the accuracy how more effectively improving coal and non-coal prediction is crucial.Native system can reflect coal and gas prominent distortion and pressure characteristic intuitively, and the phenomenon utilizing the coal and rock deformation values before giving prominence to sharply to increase reaches the object of prediction and forecast.And rule and mechanical speed clock and watch have been installed in firm firm backing plate top, roadway surrounding rock displacement size and rate of strain can be shown and the danger classes reflected, there is forewarning function more accurately;
Two, in order to solve the common bolt defect that Anchor Agent can overflow along screw thread to body of rod direction or Anchor Agent can not fully contact with anchor rod body with rock stratum etc. when mounted.The utility model devises a kind of distinctive scalable disk in the anchored end of anchor pole, it can stop Anchor Agent not overflow to body of rod direction, ensure that (Anchor Agent, rock stratum and anchor pole bond fully) anchored end anchoring strength is enough firm, reach the object improving anchoring strength;
Three, the utility model forms entirety by real for each entity part, is then close to boring, anchor pole is squeezed into tunnel, fixed.The supporting and protection structure formed has compact and ingenious structure, the feature such as easy for installation, adaptable;
Four, the utility model body of rod hollow, interior bar in the certain distance of body of rod internal slide, thus can realize the retractility of the whole body of rod, has adapted to the large deformation situation of high methane roadway surrounding rock;
Five, this anchor rod system can also be used for supporting and the forecast of coal mine rock burst, metal mine rock burst etc.
