Impact ground pressure preventing method of full seam gateway
ActiveCN104806265AImproved anti-shock performanceEven by forceUnderground chambersBlastingSupporting systemEngineering
The invention provides an impact ground pressure preventing method of a full seam gateway. The method is that an impact preventing support consisting of energy absorbing steel beams and energy absorbing anchor rod ropes is added on the basis of the general support composed of an iron wire net, a steel belt and an anchor rod, wherein the energy absorbing steel beams are lengthways distributed at intervals along the gateway, comprising two layers of steel plates, and energy absorbing boxes which are fixed at intervals between the two layers of steel plates; gateway surrounded rock in a propping plate and two sides is drilled and grouted, so that the gateway surrounded rock can damp the impact; two bottom corners of the gateway within the advance influence range of a workface are blasted to release pressure. According to the method, the general support, the impact preventing support, the surrounded rock modification and the blasting and pressure release of the bottom corners of the gateway are synchronously carried out to form a point-line-face-body 3D distribution type energy absorbing and impact preventing system; the incident stress wave can be reduced through the support system, and the reflecting stress wave of the gateway surface can be reduced; the modified loose surrounded rock mass can greatly reduce the influence of the impact energy on the support structure; the four measures supplement each other and synergistically interacted, so that the impact ground pressure preventing capacity of the gateway can be greatly improved.

The detection channel can be used for a plurality of passing objects to pass together, the existing building layout of a production workshop is not changed, the transformation period is short, the cost is low, and the space utilization rate of the production workshop is high; furthermore, the passing method is applied to the detection channel, and the collision of passing objects passing in opposite directions is avoided, so that the passing efficiency is improved, and production safety accidents are prevented.
