摘要
大倾角中厚煤层综采的开采在国内是较成熟的技术，但在攀煤公司属于迄今为止尚未解决的难题，本文对大倾角中厚煤层综采的成套设备配套的关键技术进行了研究，提出了合理确定成套设备配套的方法，即液压支架、采煤机、运输机等设备的技术性能、生产能力、空间位置和相互连接尺寸的最佳匹配问题。解决了大倾角中厚煤层综采在生产过程中面临的支架下滑、倾倒、架前冒项、支架顶梁接顶不实、采煤机在大倾角工作面上行困难、运输机下滑及工作面回采工艺复杂等技术难题，同时对支架工作阻力的确定、采煤机、运输机的选型等关键技术进行了研究。
研究采用数值模拟、理论计算和现场实践相结合的方法，通过攀煤公司大宝顶矿4221．26工作面六个月的开采试验，工作面累计生产原煤19．6万t，月平均产量达到3．26万t，最高月产量达到4．5万t，证实了此次研究选择的大倾角中厚煤层综采成套设备在技术上是可行的，安全上是可靠的，经济上是合理的。
所选设备在大倾角中厚煤层工作面能正常运行，证明了成套设备配套选型合理。
本文开展的研究对攀煤公司的大倾角中厚煤层开采具有极大的意义，能使今后生产高度集中，生产系统简化，为现代化矿井的科学管理创造了条件，为建设现代化矿井打下了良好基础。

ABSTRACT
Fully—mechanized coal mining technology in medium-thickness seam、Ⅳitll largedip angle is matured in chilla．But to PanZhihua coal corporation；it is still an unresolved problem for a long time．In this thesis，the key technologies of fully·-mechanized coal mining face unit and its optimization in medium—thickness seam with large dip angle was researched，then some methods how to Select and assemble equipment correctly Was given，such as optimization of powered support,coal wining machine，conveyor and other equipements in technology capability,
location-space and conect size with each other．According to the research,production process problems of fully-mechanized coal mining technology in medium-thickness Seam谢th large dip angle had been worked out，these problems include falling or incline of supports，roof falling before supports，roof beam not solid讲m roof,shearer push up inconvenience and conveyor slip downward in large incline coal face and other complex coal wining technology problems．
Associate谢m actual situation，adopting numerical simulation and theoretical calculation methods，the authors made a mining test吨in 4421—26 working face of DaBaoDing coal mine，after six—month ming testing，cumulative production of raw coal up to 196，000 ton,average monthly production reached 32，600 ton,the highest monthly production reached 45，000 ton．The testing cort_firmed the selection and assemble of Fully·-mechanized equipments in medium·-thickness seam with large dip angle is technically feasible，and security reliable and economically reasonable．
Equipmenst selected for medium-thickness seam wi廿l large dip angle Can continue operation,it also proof the selection for full set of equipment is correct．
Through this research on fitting and application of fully-mechanized equipments in medium-thickness Seam with large dip angle angle，it is great significance in the future coal mining to PanZhihua Corporation for the production of highly concentrated and simplified production systems．111e modernization of the scientific management of the mine has created conditions and building a modem mine laid a good foundation．
Keywords：large dip angle，medium-thickness seam，fully—mechanized coal mining working face，fully—mechanized equipments fitting
