针对深部近距离煤层群在蹬空开采条件下,动压巷道受多次采掘影响、变形严重、难以支护和维护等技术难题,采用现场实测分析的方法,通过对安徽省某矿1282(3)工作面采场及两巷矿压进行了实测研究。结果表明,当留设180 m大巷保护煤柱时,初采期间老顶来压程度不均匀;停采前,风巷超前支承压力影响区范围在煤壁前方140 m左右,支承压力剧烈影响区在煤壁前方22 m左右。停采50 d后,大巷的变形速率逐渐稳定,保证了矿井高效安全生产。 Aiming at the technical problems of deep and short distance coal seam group under the conditions of evacuation and mining under open-pit mining, dynamic pressure roadway affected by multiple extractions, serious deformation, difficult support and maintenance and so on, ) Face stope and two alluvial pressure conducted a measured study. The results show that when the coal pillar is 180 m, the pressure of the old abutment during the initial mining period is not uniform. Before stopping the mining, the influence range of the advance support pressure of the wind tunnel is about 140 m in front of the coal wall, and the supporting pressure has a drastic effect The area is about 22 m ahead of the coal wall. After the 50-day stoppage of mining, the deformation rate of the roadway gradually stabilized, ensuring efficient and safe mine production.
