摘要针对大同石炭系坚硬顶板特厚煤层开采造成的强矿压显现及控制难题，通过现场实测和理论分析，揭示了大空间远、近场岩层失稳破断的强矿压显现机制，提出了坚硬顶板控制技术。研究表明：近场岩层破断失稳造成工作面复合周期来压显现，远场结构失稳是工作面强矿压的主要影响因素，临空开采、煤柱赋存条件下，高位结构破断回转、应力集中更复杂，采场矿压显现更强烈。提出井上下、远近场协同控制坚硬岩层技术体系，通过采用井下近场预裂和地面远场压裂的坚硬岩层弱化技术，减弱远、近场坚硬岩层的矿压作用，控制工作面强矿压显现，开辟了采场矿压控制的新途径。

Abstract：The strong strata behavior and the corresponding control technology in mining the super-thick coal seam with hard roofs were studied with field test and theoretical analysis to reveal that the mechanism of strong strata behavior and an effective control technology was proposed in this paper. The results show that the breakdown of near field results in a compound periodic weighting in working face，and the instability of far field strata is the main factor that causes a strong strata behavior. The working space experiences stronger strata behavior when it is mined around gob area and under coal pillars because of a more complicated fracture and stress concentration in the high-level hard strata. The architecture of control for the near-far strata with the methods of presplitting underground and hydraulic fracturing in the ground was put forward. Thus，the pressure effects of the hard roofs in near-far field are weakened and the strong strata behavior is effectively controlled. This controlling system presents a new approach to manage the mine pressure.

Key words： mining engineering large space hard roofs strata behavior presplitting underground hydraulic fracturing
