Preparation of the conclusion. popup.stage_title Head Usov Oleh O., Registration Date 24-02-2021 Organization Institute of Geotechnical Mechanics named by N. Poljakov of National Academy of Sciences of Ukraine popup.description2 The object of study is the coal seam and host rocks. The subject of the study is the effect of moisture on the condition of the coal seam and the host rocks. Purpose: to determine the effect of water on the stability of host rocks and the feasibility of pre-humidification of coal in the array. Research methods: analysis of mining and geological characteristics and results of injection into lava analogues. As a result of this work, a conclusion was made about the negative impact of water injection on the stability of host rocks and increase the risk of treatment, as well as the inexpediency of using pre-humidification of coal in the array.  Product Description popup.authors popup.nrat_date 2021-02-24 Close
