The authors reviewed and improved the methodology for calculating fastening elements of the suspended pipes in the explosion-proof bulkhead, when it is exposed to a shock wave, with taking into account influence of angles of the fastening element inclination relatively to the vertical and horizontal planes of the roadway. For determining forces in the fastening elements of the suspension with accounting influence of angles of vertical and horizontal working planes, and for choosing a suspended pipe fastening bearing the greatest load, three types of the suspended pipe fastening were considered for mounting explosion-proof bulkheads in the belt road 2, longwall №10, of the private joint-stock company “Pokrovskoye”. A scheme is proposed for calculating the suspended pipe elements to be fastened to the structural elements of the arch support. By applying an analytical method based on the laws and regulations of theoretical mechanics, a coefficient k formula is given, which takes into account angles of the elements fastening relatively to the horizontal and vertical planes with the view of obtaining more accurate calculation of the forces acting in the elements of the suspended pipes fastened to the elements of arch support and choosing proper diameters for them in the existing normative documents. In the article, three schemes of the suspended pipe fastening are considered. An actual load on the suspended pipe fastening elements are calculated with accounting coefficient k, and discontinuity of the fastening elements are calculated for the three types of the suspended pipe fastening and their chosen sections. The proposed types of fastening of suspended pipes in the explosion-proof bulkheads and their calculation will allow the head of an accident liquidation service to choose the type most suitable for practical implementation in specific circumstances and, therefore, to improve safety of miners. On the basis of the considered types of suspended pipes fastening to the structural elements of the arch support and calculation of the occurred reactionary efforts caused by the shock wave, the authors of the article recommend to fasten suspended pipes by six chains because this type is more reliable and requires essentially less labor content when making the fastening elements for the suspended pipe by using combine or conveyor chains available at the mine.
