Abstract

1. Способ подготовки обводненного газонасыщенного массива горных пород к разработке подземным способом, включающий бурение дренажно-дегазационных скважин до начала очистных работ, откачку подземных флюидов и их утилизацию, отличающийся тем, что бурение скважин осуществляют в направлении сверху вниз в зоны повышенной трещиноватости и проницаемости за пределами подготавливаемой горной выработки, в непосредственной близости к ее профилю, выполняют откачку газонасыщенных дренажных рассолов до установления уровня депрессионной кривой ниже горизонта очистных работ и поддерживают ее на этом уровне весь период отработки.2. Способ по п.1, отличающийся тем, что при бурении скважин минимально допустимое расстояние к профилю подготавливаемой горной выработки принимают из расчета 0,035 м на каждый погонный метр скважины.1. A method of preparing a watered gas-saturated rock mass for underground mining, including drilling drainage and degassing wells before starting treatment work, pumping underground fluids and disposing of them, characterized in that the wells are drilled from top to bottom in zones of increased fracturing and permeability for outside the prepared mine, in close proximity to its profile, pump out gas-saturated drainage brines to establish the level of the depression curve n below the horizon of sewage treatment and maintain it at this level for the entire period of mining. 2. The method according to claim 1, characterized in that when drilling wells, the minimum allowable distance to the profile of the prepared mine is taken at the rate of 0.035 m per linear meter of well.
