摘要
复合顶板控制难度很大，尤其是受到断层影响的复合顶板控制更加困难。针对平煤六矿深部煤层综采工作面破碎顶板，特别是复合顶板的特性，详细分析和研究了综采工作面复合破碎顶板控制工艺的特点，合理优化顶板控制工艺，采取上网、超前支护等综合管理措施，逐步摸索出了工作面复合破碎顶板控制的有效造径，为煤炭安全回采奠定了坚实的基础。
Compound roof control,especially the control of compound roof which affected by fault is vrey difficult. Aimming at the char- acters of broken roof, especially the compound roof in No. 6 Coal Mine of Pingdingshan Coal Group,the article analyzed and researched the featares of compound broken roof control technology in details, optimized the roof control technology reasonably, and used comprehensive managements such as anchor net and advance support. The effective ways of broken roof control on fully mechanized face were put forward gradually,which gave a solid foundation for the security of coal winning.
