Abstract: Aiming at the problem of how to remove hilt quickly, economically and safely in high mining height working face, three design schemes of removing hilt technology were proposed, including advance stopping mining method, direct penetration method and filling penetration method, which combined with the characteristics of easy coal wall spalling, giant facilities, severe mine pressure appearance and large section of withdrawal channel. The advance stopping mining method means that the last half of working face to be remove is ended mining in advance, and then the equipment recovery is completed by the current construction withdrawal channel. The direct penetration method is used to strengthen the support of the crossheading roadway in advance at the hilt of working face, and then the equipment recovery is completed from the withdrawal channel after the last half of working face is directly penetrated. The filling penetration method fills the crossheading roadway in advance at the hilt of working face, then the equipment recovery is completed after the working face penetration and the filling material recovery. According to the general situation of removing hilt engineering in 4321 high mining height working face of a mine, the value coefficient of three technical schemes is analyzed and calculated by using value engineering theory. The results show that the value coefficient of filling penetration method is higher than other two methods, which is the optimal technical scheme for the construction of removing hilt in this working face. From the engineering practice of removing hilt in 4321 working face, the filling penetration method has the advantages of simple construction technology, short construction period, high resource recovery rate and high safety guarantee degree, which can realize the purpose of safe, efficient and fast removing hilt in high mining height working face.
