Abstract
FIELD: mining. SUBSTANCE: method for forming isolating curtain around mine working in inter-well space includes drilling injection wells and stage-by-stage pumping of grout. Continuous recording of a number of process parameters in the course of curtain forming is provided. On completion of pumping design volume of grout in water bearing horizon average value of coefficient of absorbing capacity of each well is calculated. Values are compared to each other. Quality of isolating curtain is good if value of the above coefficients for wells grouted at final stage of isolating curtain forming is below coefficient values for wells grouted at initial and intermediate stages of curtain forming. EFFECT: simplicity in realization, possibility of on-line monitoring, reliability, and high safety of working.
