THE DEVELOPMENT OF THE PROTECTION METHODS OF THE EXTRACTION WORKINGS WITH A VIEW OF ITS REPEATED USE BY THE RIGID PROTECTIVE STRUCTURES OF THE MULTIPLE USE

Developed and justified have been the new method and the technology of the protection of the extraction workings, the parameters of the construction of the rigid protective structure, the classification of the wall and drift cojugates operating zones; the peculiarities of the voltage redistribution on the wall and drift conjugate have been established with the different forms of protection as well as the chacracter of the roof rock fall with use of the new method of protection. The expediency of the extraction working protection by a new method has been proved; the technology of protection of the extraction workings by the new method has been developed, the field of its application has been determined; the diagram of the conjugates operating zones with cleaning works has been added. The technology of the extraction working protection has been developed and introduced in practice; the parameters of the rigid protective structure have been developed and the field of its application has been determined; the new classification of the operating zones of the drift and wall conjugation has been developed. The developed technology allows to refuse from the coal pillars, packing stripes and expensive materials and equipment required for installation of the protective belts with the deficinits conditions. The field of application: the protection of the extraction working with the barrierless its protection on the plasts with power of up to 1,5 m and angle of fall to 18 degrees with the average-fall roofs of any strengthAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
