摘要
覆岩破坏高度对于煤矿瓦斯以及水灾害防治具有重要意义。从覆岩破坏空间形态、覆岩破坏机理、覆岩破坏研究方法三个方面详细阐述了中国煤层开采后覆岩破坏高度存在的问题。并针对目前存在的问题,提出了相似模拟法数字岩心以及3D打印还原岩心技;未来现场测试从工作面开采时进行直到整个工作面回采完毕的实时监测技术;先总结各矿区的覆岩破坏高度经验公式,进而提出适应目前开采工艺的经验公式;模拟软件克服单一条件的模拟,能够结合众多影响覆岩发育规律的条件进行模拟。
The failure height of overburden rock is of great significance to the prevention and control of gas and water disasters in coal mines.From three aspects:the space form of overburden failure,the mechanism of overburden failure and the research method of overburden rock failure,the existing problems of overlying rock failure height after coal seam mining in China are expounded in detail.Aiming at the existing problems,the digital core and 3D printing and reducing core technology of similar analogue method,real-time monitoring technology of field test from face to face are put forward until the whole face is finished.The empirical formula of overburden failure height in each mining area is summarized firstly,and then the empirical formula adapted to the current mining technology is put forward,and the simulation software can overcome the simulation of single condition and can be combined with many conditions that affect the overburden development law.
