底鼓是煤矿深部开采巷道中最常见的现象之一,也是目前地下开采特别是深部开采面临的急需解决的工程问题。为了保证矿井的安全高效生产,尽量消除底鼓对生产的干扰,前人在经过很多的研究和实践的基础上提出了一些限制底鼓发生及限制底鼓量的方法。这些方法按照各自机理的不同分为:支护加固法、卸压法和联合支护法。 The bottom drum is one of the most common phenomena in mining deep mining roadway, and is also an engineering problem that needs to be solved urgently in underground mining, especially deep mining. In order to ensure the safe and efficient production of mines and to try to eliminate the interference of the bottom drum with the production, previous studies have put forward some methods to limit the occurrence of the bottom drum and limit the amount of bottom drum based on a lot of research and practice. These methods are divided according to their different mechanisms: support reinforcement method, pressure relief method and joint support method.
