Proposed starter comprises four excitation permanent magnets, motor start draught relay, free-running ratchet clutch (FRC) and planetary reduction gear. Carrier of the latter is engaged via spline with free-running clutch drive case stem. Draught relay solenoid and terminal box are arranged inside the motor stator cover and aligned with its lengthwise axis. Electromagnetic oil core represents the FRC stem, drive gear of the latter being located at initial position on opposite side of flywheel rim with the help of longer mid bush part there between. Bush diameter is smaller than that of driven gear dents circumference. Starter motor armature shaft is integrated with planetary reduction gear sun gear with its stem running in carrier movable shaft. Starter reduction gear epicyclic gear and electromagnetic oil case are made integral of caprolon. Two covers and starter motor stator are coupled by two isolated studs with coppered contact heads that make the electrical conductors. The latter extend through holes made on starter motor stator cover outer side. Two parallel guide rectangular slots of its radial ledges and caprolon rectangular inserts accommodate two parallel contact rectangular rods of fork-like contactor with copper solderings on their ends for making rectangular coppered contact heads of aforesaid studs. Theses separate their contact cavities from ICE clutch case and rule out the ingress of oil and foreign particles to starter terminals. Central cylindrical holes of coil case, on one side, are radial thrust bearing for planetary reduction gear carrier stem. On the other side, these make the guide for FRC helical return spring arranged between end surfaces of FRC drive case and end splined screw bush. The latter is fitted on carrier shaft splines to rest via thrust carrier shaft bush on radial thrust bearing of coil case. This allows to reject split antifriction bearing fitted in coil case and plenary reduction gear shaft thrust flange. Note here that carrier shaft is made of nonmagnetic steel and fitted to carrier stem of magnetic steel on one side and, on the other side, it is fitted in starter motor cover antifriction bearing. With draught relay IN, movable steel fork-like contactor displaces along the FRC in two parallel guide slots for making rectangular coppered contact heads of starter motor starting studs. Coil pull-in magnetic force and shaped return spring expansion force FRC return spring is contracted and held thereat at starting the starter motor. With draught relay in OFF, drive gear with RFC and moving fork-like contactor return to their initial position to radial thrust bearing of starter motor stator cover under action of FRC return spring force. This contracts the shaped relay spring and holds its as-contracted unless draught relay actuation. At a time, draught relay displacement and contraction are performed by the forces of inertia of FRC driven gear and force of friction developed at driven case overrunning of drive case after ICE starting between their end surfaces pressed from both sides by RFC return spring and shaped relay spring. |

Method of forecast of location of lower boundary of explosive gas zone in stope Method of forecast of location of lower boundary of explosive gas zone in working face is proposed, comprising the driving of bypass in working area, implementation of well into the top of layer, and measurement of methane concentration along its length by the moving gas metering probe. At that the well into the top of layer is carried out from the junction of lava with adjoining air release working in the direction of the worked-out area of the current working area to placement of immediate mine roof to the length equal to its pitch of placement, at an angle of unloading of roof rocks from moving boundary of the stope. The measurement of methane concentration is made along the length of the well with the forward and reverse movement of gas measuring probe in preassigned intervals of length of the well, and the lower boundary of explosive gas zone is set from the top of layer along the lower concentration limit of explosibility of gas-air mixture. |

Method of construction of geologic model for oil and gas deposits Method includes core analysis, lithologic sectional layering, plotting of lithologic and stratigraphic columns (considering textural and structural diagnostic properties), interpretation of well survey materials, identification of the examined object and definition of correlation dependence, performance of mapping, paleoreconstruction of depositional conditions for the examined object considering ratios of natural radionuclides (thorium and uranium). At first the core is described by studying and identifying lithologic and structural features of rock porosity and permeability properties, thereafter the core is photographed in day light and ultraviolet light, profile and physical and chemical researches are performed. Then lithologic sectional layering is made with plotting of lithologic and stratigraphic columns considering textural and structural diagnostic properties. Then materials of well surveys are interpreted, analysed and obtained results are checked against identified correlation dependence, and detailed objects of study are identified. Further by mapping methods analysis is performed for identified dependences, which characterise the object of study by geologic, lithologic, petrophysical, geochemical, geophysical, structural, dynamic, tectonic and other signs of the object of study. On the basis of earlier acquired and processed data geological model of the deposit is formed using methods of facies map reconstruction for depositional conditions considering ratios of natural radionuclides (thorium and uranium); boundary of marine conditions transition to continental "sea-land" conditions for depositional conditions in the model. |

Plasma gun contains an outer electrode, an inner electrode holding the cathode and placed coaxially, a vortex chamber feeding plasma-generating gas. The electrodes are insulated and placed in induction coils. The inner electrode holding the cathode is made hollow. Methane hydrocarbons are fed to curved channel of the outer electrode through outlet channels and circular cavity. To near-cathode area methane hydrocarbons are fed through a tube placed at the axis of the inner electrode holding the cathode and cavity formed by location of the cathode in the hollow electrode holding the cathode. The plasma gun has at least four channels for hydrocarbon gas delivery to the near-cathode area of arc discharge. The channels are placed evenly in circumferential direction. Total area of the channels open flow area provides gas velocity of about 0.3-0.5 of sound speed at the preset complete pressure and temperature of the feed gas. Delivery of hydrocarbon gas to the near-cathode area of arc discharge is designed in three versions. |
