Altitude-action pyrotechnic article Proposed article comprises the case with blowout charge located at its bottom, electric igniter and blasting fuse. Note here that compartment with gas generating substance is added to this article. Besides, soft inflatable shell connected with compartment neck is arranged at top part of said case. Compartment base is connected via blasting fuse with blowout charge. |

Drilling and blasting operations at open pits Proposed method comprises drilling of parallel rows of wells, charging them with explosives and their short-delay blasting. This short-delay blasting of radially arranged charges in membrane layers is performed as follows. First row of wells is blasted, the third one from the bench edge. Then, 1 row of wells is blasted with 25 ms delay while 2 rows of wells are last blasted with 50 ms delay. To locate the membrane layers, rock mass is photographed to define the radius of curvature of bench mining block slope by relationship with due allowance for acoustic stiffness of rocks. Weighted average layer-by-layer quantity of systematic fractures per the width of mining block coverage Wc is defined. Weighted average spacing between two adjacent systematic fractures is defined. Degree of crushing and line of resistance at bench bottom are defined. Sums of rock bed depths and strength factor (by Protodyakonov scale) are calculated. Rock strain rate, clamp factor, explosive potential energy and blast efficiency are defined. |

Method of charge gas dynamic centring and device to this end Proposed device comprises barrel with breech closed by dual striker mechanism body and internal sleeve with lengthwise channel. Live round consists of cartridge with fuse and powder charge and billet arranged in sleeve with clearance and connected with said channel via grooves and drags composed by small-diameter bores arrange din groups along said barrel, each making a row of bores equally spaced in circle. Axes of said bores can make an angle with barrel radius line. Extra pressure source (blank cartridge) is arranged in cartridge and communicated with said channel via the bores and makes the high pressure cylinder or compressor. Said sleeve consists of pipe lengths with end surfaces whereat at arranged are said drags. On combustion of powder charge in cartridge, billet starts displacing in barrel. At a time, powder combusts in cartridge to make powder gases surpass the billet to flow in bore, channels, grooves and openings into barrel Biller body stopping barrel bores cause bearing gas ply to be created to centre the billet. |

Jet round with optical target sensor Target sensor is arranged inside nose fuse case. Protective jacket, nose retainer, pyro drive, electronic time and bottom retainer are arranged on fuse case. Said case is composed of shell-type body of revolution following, preferably, the fuse outer outlines. Said case is arranged on fuse outer side. Said case consists of three and more segments. Nose retainer is arranged at protective jacket head part. Pyro drive is arranged at fuse case to allow axial displacement of nose retainer. Electronic timer outputs are connected with pyro drive outputs. Bottom retainer interacts with bottom parts of protective jacket segments to lock the latter at fuse case in radial direction. Protective case segments have structural elements interacting with mating structural elements of fuse case to rule out displacement of segments relative to fuse case at activated head and bottom retainers. |
