摘要
为实现淋水条件下的安全支护,综合现场调研、实验室实验、理论分析、井下试验等方法,对巷道变形机理、煤岩体强度变化等开展了研究,提出采用防水锚固剂、注浆加固等措施,实现对该类巷道的稳定性控制。
In order to realize the safety support under the condition of water leaching,the deformation mechanism of roadway and the strength change of coal and rock mass were studied by means of field investigation,laboratory experiment,theoretical analysis,underground test and so on.Measures such as waterproof anchoring agent and grouting reinforcement are proposed to realize the stability control of this kind of roadway.
