摘　　要：基于我国是一个煤炭资源比较丰富的国家,储量大,地质条件复杂,给我国煤炭的开采带来了许多这样那样的问题,在复杂地质条件下回采工作面,受断层、老巷等地质构造影响,工作面极易发生歪架、顶板事故,严重影响工作面生产。因此,如何将有限的煤炭资源进行开采以及利用就显得尤为重要,如何科学合理的控制好顶板,保证矿井安全高效的将原煤进行开采利用,对煤矿企业高产高效具有重要意义。Based on the fact that China is a country rich in coal resources,with large reserves and complex geological conditions,many such and such problems have been brought to China’s coal mining.Under the complex geological conditions,the working face,affected by faults,old lanes and other geological structures,is prone to occurrence of askew frame and roof accidents,which seriously affects the production of the working face.Therefore,how can the Limited It is very important to mine and utilize the coal resources,so how to control the roof scientifically and reasonably to ensure the safe and efficient mining and utilization of the raw coal is of great significance to the high-yield and high-efficiency of the coal enterprises.
