Essay

The paper is devoted to subsidence process parameter relationships investigation for plane coalseam second working. Depth parameter influence on new subsidence process parameter relationships are obtained. Different metamorphism extent influence on average tensile deformations velocity along plane subsidence have investigated. Tensile - compress endurance phase sequance are investigated. Thereto, main roof-caving increment and advance stope rate is determined. The method of application of calculation of endurance of the process displacement of a rock mass and surface is designed. On its(her) ground(basis) the methodical indicatings for fulfilment of laboratory operation on a speciality "mine surveying" for the students are compounded. Advance stope rate dependences are obtained for condition when tensile deformations not expand to watery strata. The guidelines for design entities on calculation of arguments of the process displacement in intercoupling with speed of progressing of deformations in a massif and speed of movement refining are designed.
