【外文文献】1The thin coal bed synthesis picks the equipment the development and the craft parameter optimizationMainly discussed the thin coal bed synthesis which Zaozhuang Mining industry Group Company independently developed to pick the equipment in Tian the Chen Kuang success application, and to its supplementary equipment technological transformations and the technical characteristic, the working surface geological condition, the synthesis picked the equipment the craft parameter optimization and the working surface working procedure reasonable match safeguard technology measure has carried on the thorough analysis and the introduction.Because the thin coal bed its mining space is narrow, the efficiency is low, the working surface condition is bad, machinery equipment not necessary or mining coal craft imperfect and so on technical questions, difficulty with realizes the mine pit highly effective and the safety in production. Zaozhuang Mining industry Group Company profits from the experience which my guozhong thick above coal bed synthesis picks, picked the supplementary equipment in the thin coal bed synthesis the development and the craft parameter optimization aspect has carried on the beneficial exploration.In October, 2003, ore 531 working surfaces equipped in its Tian the Chen has independently developed and the improvement three machines supplementary equipment, has obtained the tangible effect, realization maximum daily production 3504t, the average month produced 89636t, created the roller thin coal bed synthesis to pick the unit to yearly produce 1,000,000 ton new levels.Equips this working surface equipment fund investment is 1088.10 Yuan, the equipment does not invest into the equipment coal plow surface 1/10. First, the synthesis picks the three machines necessary and the technical characteristic (1) hydraulic pressure support According to the thin coal bed mining characteristic, uses the computer to carry on the movement analysis optimization and the intensity design to the support four link motion gears, satisfies the working condition, optimized the support structure: (1) support for the support shield type, has used the overall top-beam, two column supports has satisfied the big expansion and contraction request; (2) main structural element with the Q550 high strength structure steel plate manufacture, reduced the support weight.Front uses welds preheating, after welds the artificial aging welding craft, the guarantee structural element welding quality; (3) selects the great current capacity hydraulic pressure part, enhances the support the speed of response; (4) reasonable arrangement hydraulic circuit system, has enlarged the human, machine the space. Its development ZY2400/08/19 hydraulic pressure support technical characteristic is as follows: Two column support shield type, support 0.81.9m, support width 1.431.6m, center distance 1.5m, working resistance 2400kN, supports and protections intensity 0.410.46MPa, the adaptation inclination angle is not bigger than highly 35, operating mode for neighbour control, support weight 6500kg. (2) coal mining machine Unifies thin coal bed mining the technical characteristic, has carried on the transformation to the coal mining machine following several aspects: (1) improvement design pump box, the solution gives off heat the question, satisfies the synthesis to pick the operation percentage high operating mode need; (2) designs a group of tapering spindle rocking shaft specially, causes the drum circle diameter to reduce, increases the leaf blade altitude correspondingly, does an inside job the quantity request satisfiedly; (3) optimized drum design, increases the leaf blade spiral angle of climbing reasonably, the improvement coaling effect; (4) decreases the fuselage suitably highly (824mm), coal mining machine each big joint place has made the corresponding improvement. After the transformation coal mining machine MG200-BW2 technical characteristic is as follows: Picks high scope 1.02.0m, the adaptation inclination angle is not bigger than 35, the adaptation coefficient of hardness f3.5, drum diameter 800/1000mm, machine surface altitude 824mm, does an inside job measures 91mm, the hauling way for the non-chain hauling, biggest force of traction 250kN, hauling speed 06.14m/min, installing equipment power 200kW, voltage rank 660/1140V, machine gross weight 15t, machine total length 7858mm. (3) scraper conveyer Mainly has carried on the transformation to the scraper conveyer in following several aspects: (1) has used in the thin coal bed scraper conveyer the double strand transmission structure, loses the coal condition to be able to improve; (2) home for the first time used middle the 22E trough section on the thin coal bed scraper conveyer, the complete machine rigidity, the intensity had enhances greatly; (3) reduces the nose, the airplane tail trough highly (is excessively 430mm),
