Abstract: FIELD: mining industry. SUBSTANCE: invention is related to technology of mining of new gently dipping coal seams which working is complicated by disjunctive disturbances. Process of development of thick gently dipping coal seams includes development of coal seams in layers by powered mining complex with discharge of coal benches from under roof or between layers on to conveyer of complex-powered breakage face. First upper layer of seam containing disjunctive disturbance is developed with entry into zone of seam disturbance from side of fault. Difficult to cave top of seam is converted to category of easy or medium caving with the use of advanced shot-firing operations in rocks of seam top or by method of hydrodynamic stratification of rocks of seam top. Footing of seam is developed by entry into disturbance zone of seam from side of reverse fault. After passage through disturbed zone of seam powered mining complex is transferred to seam ground and the rest of excavation column is worked with discharge of coal from interlayer bench. Operation of transfer of powered mining complex to seam ground is executed upon its complete passage through disturbed part of seam.

Abstract: FIELD: manufacture of plant covers used for beautification of streets, squares, construction of sportive grounds, as well as for landscape designing. 
     SUBSTANCE: method involves spraying organic adhesive onto fine-mesh basalt net by means of specially designed equipment for filling meshes to thereby create strong carrier base. Net is perfectly ecologically safe and allows seeds to be uniformly sown over the entire area of lawn. Adhesive used for providing lawn is functioning as nutritive compound for seeds and is used simultaneously for protecting seeds from external influence of moisture and air during prolonged periods. After drying in first drying chamber, mixture of lawn grass seeds is sown onto carrier base through dosing hopper, followed by applying onto given mixture of organic adhesive and drying in second drying chamber. After discharge from drying chamber, ready dry lawn is cut into parts of various lengths, wound into roll and hermetically packed in polyethylene film for further storage and transportation. Lawn is placed on site by unwinding roll onto preliminarily prepared ground and spilling nutrient mixture thereon, followed by heavy irrigation to provide for sprouts emergence. Nutrient mixture and lawn grass seed mixture compositions are worked out depending on climatic zone and composition of parent ground on which lawn is to be provided.

Abstract: FIELD: medicine, psychotherapy. 
     SUBSTANCE: the method combines an interrogation and psychotherapeutic discussion. Then, at the first stage a patient has got a habit to breathe at signals at their length corresponding to signal of respiratory training equipment: inhalation 2-3 sec, expiration 3-4 sec and pause 3-4 sec. From training to training it is necessary to decrease air volume used for inhalation. On training the algorithm of patient's breathing it is necessary to carry out the second stage in case of patient's comfort state. It should last for about 3 h daily. During the second stage one should decrease air volume necessary for inhalation-expiration cycle up to 0.2-0.1 l. At achieving the duration of control pause of respiration being 60-90 sec it is necessary to start the third stage to maintain the following algorithm of respiration: inhalation 2-3 sec, expiration 3-4 sec, pause 3-4 sec. At air volume necessary for inhalation at the state of rest being 0.2-0.1 l one should conduct control pause being equal to 60-90 sec as a standard. In case of deviation trainings should be performed at the volume to restore the control value. The innovation helps to get rid of tobacco smoking due to saturating patient's blood with carbonic acid. 
     EFFECT: higher efficiency of therapy.
