Изобретение относитс  к сооружению подземных выработок в водоносных породах под сжатым воздухом в горной промышленности, а также пр строительстве тоннелей, метрополите нов и коллекторов. Известен способ поддержани  горных выработок в услови х безлюдного их проведени  в водоносных породах, включающий проходку выработок и н.агн тание в них сжатого воздуха с цепью снижени  поступлени  воды в полость выработки D1 и Г23 . Недостатками известного способа  вл ютс  низка  устойчивость стенок выработки вследствие поступлени  через стенки выработки в ее полость воды и вредные услови  труда, св зан ные с тем, что работы провод тс  в атмосфере сжатого воздуха, (как следствие имеет место низка  производительность работ). Цель изобретени  - увеличение устойчивости выработки и улучшение условий труда. Поставленна  цель достигаетс  тем, что сжатый воздух, нагнетаемый в подземную выработку под давлением , превышающим гидростатическое давление грунтовых вод, предварительно охлаждают до минусовых температур . При этом вода, наход ща с  в породе стенки выработки, О1жимаетс  охлажденшд4 сжатым воздухом вглубь массива и благодар  цементации ее льдом увеличиваетс  устойчивость.выработки . Применение щ)едлагаемого способа дает возможность после замораживани  отжатой воды и герметизации стенок выработки снизить давление до атмосферного и тем самым создать нормальные услови  дл  проведени  строительных и монтажных работ в выраб.отке . Формула изобретени  . Способ поддержани  горюлс вырабо ток в услови х безлюдного их проведе (ни , включанщий проходку выработок и нагнетание в ник сжатого воздуха, :отличающийс  тем, что, с целью увеличени  устойчивости выработки и улучшени  условий труда, сжатый возду: предварительно охлаждают до минусовых температур. 83434 5 10 9 ,4 Источники информации, прин тые во внимание при экспертиз.е 1.Бокий Б.В. и др.

The invention relates to the construction of underground workings in aquifers under compressed air in the mining industry, as well as the construction of tunnels, metropolitan areas and reservoirs. There is a known method of maintaining mine workings under conditions of deserted mining in aquifers, which includes sinking workings and pressing compressed air into them with a chain that reduces the flow of water into the production cavity D1 and G23. The disadvantages of this method are the low stability of the walls of the excavation due to the entry of water through the walls of the excavation into its cavity and harmful working conditions due to the fact that the work is carried out in an atmosphere of compressed air (as a result, the productivity of the work is low). The purpose of the invention is to increase the sustainability of production and improve working conditions. The goal is achieved by the fact that the compressed air injected into the underground workout under pressure exceeding the hydrostatic pressure of the groundwater is pre-cooled to sub-zero temperatures. At the same time, the water that is in the rock wall of the excavation, O1, is cooled by compressed air deep into the massif and, due to the cementation by its ice, the stability of the production increases. The use of a) method allows, after freezing the pressed water and sealing the walls of the excavation, to reduce the pressure to atmospheric pressure and thereby create normal conditions for carrying out construction and installation works in the extraction section. Claims. The method of maintaining the fuel production in conditions of deserted people (including the excavation of workings and the injection of compressed air into the nickname: characterized in that, in order to increase the sustainability of production and improve working conditions, the compressed air: is pre-cooled to minus temperatures. 83434 5 10 9, 4 Sources of information taken into account during the examination 1.
