The thesis is devoted both to the problems of parameters' ground and to the development of the combined method of support of repeatedly used getting workings in the conditions of the intensive rock pressure. This task solving is achieved by multi-levels protective constructions usage, having base support as well as by regu-lated erection of casted rigid stripes made of solidified materials. At the expense of both construction perfection and schemes of forced stripes interaction with rock mass, the poly-compensation of rock shifts at the working as well as required carrier ability of casted stripe, corresponding to the expected load is provided. As a result of theoretical, laboratory, industrial and experimental researches both the behaviour of geo-mechanical processes having taken place around the devel-opment workings and geo-technical system deforming mechanism "base support-rock mass-protective structure" were determined. On the basis of the research of the intense-deformation system state, the parameters of location and erection of casted stripes depending on their loading conditions were grounded. To form such stripes the mineral mixture( which was covered by the patent) was suggested. The techno-logical regulations of both getting drift protection and casted stripes , made of solidi-fied materials erection of different design were developed and approved by the cer-tain branch level. SRI "Dongyproshacht" has been chosen for underground work de-sign. The suggested technological solutions were invented at the "Krasnoarmeiskaya -Zapadnaya № 1" Mine. Practically economical effect is 4,8 mln. grvn. The main content of work is presented in the monograph, eleven research articles and reports at the international symposiums and conferences and it was also summarized in the in-vention patent.
