Description
Изобретение относитс к угольной промышленности и может быть использовано- дл профилактической обработки угольных пластов.The invention relates to the coal industry and can be used for prophylactic treatment of coal seams.
Цель изобретени повышение эф фективности обработки за счет увеличени проницаемости йласта и улучшение качества угл .The purpose of the invention is to increase the processing efficiency by increasing the permeability of the core and improving the quality of coal.
Повышение проницаемости угольного пласта способствует увеличению безопасной глубины выемки, т.е. повышению безопасности ведени горных работ на газоносных и выбросоопас- ных угольных пластах. В то же врем растворение минеральной составл ющей угл позвол ет снизить его зольность и, тем самым, повысить ка- чество добываемого угл .Increasing the permeability of the coal seam increases the safe depth of excavation, i.e. improving the safety of mining operations on gas-bearing and outburst-hazardous coal seams. At the same time, the dissolution of the mineral component of the coal reduces its ash content and, thus, improves the quality of the coal produced.
Способ осуществл етс следующим образом.The method is carried out as follows.
Через скважину, пробуренную на угольный пласт, нагнетают водный раствор комплексона ИСБ-М, включающий нитрилотриметилфосфоновую кис245716 . .2An aqueous solution of the complexion ISB-M, including nitrilotrimethylphosphonic acid, is forced through a well drilled into the coal seam. .2
лоту (НТФ), сол ную кислоту (НС)., фосфорную и-фосфористую кислоты (H-jPO +H PO-j) концентрацией 1,0- 7,0%, который раствор ет соединени .lot (NTF), hydrochloric acid (HC)., phosphoric and-phosphorous acid (H-jPO + H PO-j) with a concentration of 1.0-7.0%, which dissolves the compounds.
5 металлов, вход щие в минеральную составл ющую угл , и увеличивает количество открытых пор и трещин, т.е. повышает проницаемость угольного пласта. Закачанный раствор ком10 плексона вьщерживают в пласте в течение 3-7 дн. Затем i пласт закачивают водный раствор щелочи, например NH ОН, концентрацией 0,1-0,5%, . котора переводит нерастворимые про15 дукты реакции, полученные при взаимо-; действии раствора комплексона ИСБ-М с соединени ми металлов, в растворимые и дополнительно повышает проницаемость угольного пласта.5 metals included in the mineral component of coal and increases the number of open pores and cracks, i.e. increases the permeability of the coal seam. The injected complexion plexon solution is held in the reservoir for 3-7 days. Then i layer is pumped into an aqueous solution of alkali, for example NH OH, with a concentration of 0.1-0.5%,. which translates the insoluble reaction products produced by the inter; the action of the solution of the complexone ISB-M with metal compounds, soluble and further increases the permeability of the coal seam.
20 Лабораторными исследовани ми onpev делают и шахтными исследовани ми уточн ют оптимальные концентрации закачиваемых растворов. Результаты исследований представлены в таблице.20 Laboratory studies of onpev do and mine studies specify the optimal concentration of the injected solutions. The research results are presented in the table.
