IMPROVEMENT OF A LONGWALL RECOVERY ROOM ERECTION TECHNOLOGY

The numerical analysis of the stress-strain state of the rock massif at different location the longwall erection of recovery rooms are executed. Need of accounting of value of periodic roof weighting is shown. As the pacing factors having the impact on the value of periodic roof weighting durability and power of the main roof and speed of advance of the longwall face are specified. The possibility of use of MARCO electro-hydraulic control equipment systems for exact determination of periodic roof weighting is shown. The recovery rooms erection technology providing decrease span of time and costs of moving of the longwall equipment is offered.
