针对鸳鸯湖矿区梅花井煤矿,超长距离回采巷道顶板含水条件下巷道快速掘进问题,通过对112201工作面顺槽正规循环作业各工序及其作业时间,进行统计和分析,得出了制约快速掘进的因素.据此提出了适合该条件下,巷道快速掘进一次成巷技术.主要包括采用半圆拱形巷道断面,及其巷道地坪、水沟、喷浆、调车硐室、钻机硐室、水仓等配套工程,都及时紧跟工作面,后续尾工少,掘进工作面系统工作效率得到显著提高,使得同类条件下巷道掘进速度,由原来的300m/月提高到500m/月,整体掘进速度加快.
針對鴛鴦湖礦區梅花井煤礦,超長距離迴採巷道頂闆含水條件下巷道快速掘進問題,通過對112201工作麵順槽正規循環作業各工序及其作業時間,進行統計和分析,得齣瞭製約快速掘進的因素.據此提齣瞭適閤該條件下,巷道快速掘進一次成巷技術.主要包括採用半圓拱形巷道斷麵,及其巷道地坪、水溝、噴漿、調車硐室、鑽機硐室、水倉等配套工程,都及時緊跟工作麵,後續尾工少,掘進工作麵繫統工作效率得到顯著提高,使得同類條件下巷道掘進速度,由原來的300m/月提高到500m/月,整體掘進速度加快.

For the problems roadway quick drivage under the condition of over length distance mining roadway water roof in Meihuajin mine of Yuanyanghu mining area, This text statistics and analysis of each process of 112201 working face crossheading normal circulation and its operation time and get the restricting factors of quick drivage, and put forward the technique for quick drivage and one-time finish drivage suitable the conditions. Mainly includes use section semi-circular arched tunnel, and the tunnel floor, ditch, shotcrete, supporting shunting chamber, drilling chamber, water storage and other ancillary works all timely follow the working face, the subsequent finishing less, work efficiency of excavation working face has been significantly improved, making the roadway excavation rate is increased from the original 300m/month to 500m/ month under similar conditions, the whole driving speed up.
