山寨煤矿1201综放工作面底板起伏段回采技术

Mining Technology for Floor Undulating Section at 1201 Fully Mechanized Caving Face in Shanzhai Mine

基于山寨煤矿1201工作面底板起伏变化大,对正常回采带来诸多不利因素,采用无线电波透视法对地质异常区作了详细探测,在回采中靠近凸起段时提前逐渐提底,使工作面呈弓背形仰俯采,并制定刮板输送机、液压支架调控措施,实现了工作面安全高效回采。

The big floor undulation at 1201 working face in Shanzhai Mine brings various unfavorable factors to the normal mining. Ra- diowave penetration method was used to detect abnormal geology areas in detail, the floor approaching to the bulging section was gradu- ally lifted in advance during the mining process, which made the working face show a roachback shape up - down dip mining. Control measures about scraper conveyers and hydraulic supports were made to realize the high efficient mining.
