Achievement name: The rope takes the application of engineering technology of core diamond drilling in coalfield exploration
Achievement brief introduction: This achievement developed comfortable cliff diamond bit and reaming implement, accomplish finalize the design basically, broach mean life already amounted to 52.56m/ in the Fujian Province, in Yunnan, Sichuan the province amounts to 145.74m/ , highest amount to 290.77m/ ; Increase broach external diameter, enlarge cricoid space, established the set of S75 2 drilling tool with more reasonable grading, implementation opens high rotate speed, the choice is best get into parameter, improve efficiency. Studied applicable rope gets craft to ask " 3 low one good " small firm photograph and strong lotion of the photograph that do not have solid amount to 3 kinds 6 kinds, summary protects aperture and method of shot-off of loss, use 7 kinds of plugging material; Construction of reasonable and affirmatory drilling, form give priority to drilling tool with S75 2, s59, S95 is the 3 level form a complete set of mothball drilling tool, solved problem of complex layer construction effectively.

Achievement name: Anchorage lever of MQT-85J series pneumatic (anchor cable) borer

Achievement brief introduction: This achievement basically uses at coal industry auger collect a domain. Optimize in research designed angle to change a gear type pneumatic is motor, gear uses aviation material and treatment technology, the wear-resisting that supplied gear, be able to bear or endure the function of corrupt, prolonged service life, provide have rendered great service to lead big, torque big, fight contaminative ability strong, construction is reasonable wait for a characteristic, hard terrane and anchor cable are deep in can suiting of aperture get authentic. Developed 2mm to press colophony, machinery to twine without dip of cloth of the alkaline fibre glass that do not have candle, exterior spray technology, raised foot to advance the shear strength of the orgnaization, assured the wearability of air leg, lubricity and sealed dependability, reduced overall weight. Current, through 50 many mine many 380 use, satisfied spot construction requirement completely, and drilling rate rose 40% .

Achievement name: JDGKS-21 Electromechanical is amphibious self-propelled aerial work truck

Achievement brief introduction: This achievement is with " diesel engine " or " report " regard motivation as the source, respectively the hydraulic pressure oil pump that drive is linked together to it produces high-pressured oil, through controlling the operation of the handle, high-pressured oil will be direct action at adjustable, luffing, rotate and walk orgnaization, produce corresponding action, basically use at dust big, temperature grain of the horniness in big, air counts tall, humidity a lot of abominable work environments. Main technique index: In the job rated load: 300kg; In the job height of the biggest operation: 21m; In the job radius of the biggest job: 18m; Limits of working arm luffing: - ° of 10 ° ~72; Wear body corner coming back to spend: 360 ° ; Walk speed: 1.2km/h; Main control system is the oldest pressure: 17.5MPa; Complementary control system is the oldest pressure: 14.0MPa. Achievement name: Test trying oil evaluates a system
