摘要

FIELD: mining engineering.;SUBSTANCE: method is applicable for controlling a crack in overlapping rock and saddling of surface in the course of mine development with water conservation. The sensor is mounted at the top of mined out space for face backfilling, where extraction with water conservation is perfomed, the main backfill portion is monitored with stress indication device to determine whether the backfill contacts with the back of mined out space or they are separated. When the main backfill portion is separated from the back after contact with the back is established, the backfilling of the mined out space is filled-up to achieve complete contact with the back in order to obtain control over cracks in the overlapping rock and saddling surface and ultimately protect water resources when performing mine operations in the mine.;EFFECT: simple and targeted method with reliable functionality and high efficiency.;2 cl, 2 dwg
