摘要
通过现场实测,对中平能化集团十矿戊9-11-20102大倾角下分层综采工作面矿山压力显现规律进行研究,结果表明:工作面周期来压呈现出分段来压现象,具有局部来压和来压逐渐迁移的特点,周期来压步距为12～23m。针对工作面下分层破碎顶板管理和设备防倒、防滑措施进行研究,并在中平能化集团十矿戊9-11-20102工作面进行现场应用,取得了较好的技术经济效果。
With the site measurement, a study was conducted on the mine strata pressure behawor law ot the fully mechanized coal mining face in the low slicing seam of the WU 9 - 11 - 20102 deep inclined seam in No. 10 Mine of Zhongping Energy and Chemical Group. The results showed that the periodical strata pressurized of the coal mining face would have a sectional pressurized phenomenon and would have the features of the local pressurization and the pressurization steadily migrated. The periodical pressurized step distance would be 12 -23m. A study was conduced on the broke roof management of the coal mining face in the low slicing seam and the falling prevention and sliding prevention measure of the equipment. The study results were applied to the WU 9 - 11 - 20102 coal mining face in No. 10 Mine of Zhongping Energy and Chemical Group with good technical and economic effects.
