The article contains the results of application in a coal mine of a combined way for protection and support of development workings. This method combines a frame support, anchors and a cast support strip erected behind the longwale. The geomechanical substantiation of technological parameters, regulations and the field for efficient use of this method are given. Its introduction has allowed to increase the loads on longwale and to lower labour content and expenses for maintenance of butt entries.
During planning of mining works with coal series it is important to take into consideration mining conditions of each mine layer, to determine presence of natural and technogenic abnormal areas at its place and to appreciate their potential level of influence on the increase of rock pressure manifestations in the development and productive workings. In comparable conditions the most negative manifestations of rock pressure can be observed in roadways of neighboring low layer, when they are disposed in range of mutual action of abnormal areas of natural and technogenic origins.
