摘 要:近年来,随着煤矿开采向深部不断延伸,鹤煤公司采掘接替普遍紧张。鹤煤公司普遍采用传统炮掘掘进方式,掘进速度及工效普遍较低、成本相对较高,采用机械化作业线来提高掘进速度,是缓解目前采掘接替日趋紧张的局面的重要措施。本文以鹤煤三矿4204底板抽采巷(下)为工程研究对象,通过对掘进装备的选型及施工工艺的优化,研究岩巷综合机械化掘进作业线应用。实践表明,岩巷掘进速度有大幅提高,实现了高效掘进的目的,保证了矿井采掘的正常接替。

Abstract: In recent years, with the continuous extension of coal mining to the deep, the mining replacement of Hemei company is generally tense. The traditional blasting driving method is widely used in He coal company. The driving speed and work efficiency are generally low and the cost is relatively high. It is an important measure to improve the driving speed by using mechanized operation line to alleviate the increasingly tense situation of mining replacement. In this paper, 4204 floor extraction roadway (lower) of Hemei No.3 Mine was taken as the engineering research object. Through the selection of tunneling equipment and the optimization of construction technology, the application of comprehensive mechanized tunneling line in rock roadway was studied. The practice shows that the driving speed of rock roadway is greatly improved, the purpose of efficient driving is realized, and the normal replacement of mining is ensured.

近年来,随着煤矿开采向深部的不断延伸,鹤煤公司采掘接替普遍紧张。鹤煤公司普遍采用传统炮掘掘进方式,掘进速度及工效普遍较低、成本相对较高,岩巷掘进和瓦斯治理工程量的增加导致矿井接替进一步紧张,巷道掘进已成为制约煤矿高产高效的重要环节。目前,劳动力缺乏及劳动力成本持续增加,采用综合机械化作业线来提高掘进速度,成为缓解采掘接替日趋紧张的局面的重要措施[1-4]。本文以鹤煤三矿4204底板抽采巷(下)为工程研究对象,通过对掘进装备的选型、支护工艺的优化、快速掘进工艺的研究,分析了综合机械化快速掘进技术在岩巷掘进中的应用,并为相同地质条件下岩巷快速掘进提供理论依据和参考。
