摘 要:门克庆煤矿井下主排水泵房,设计长度69.868m,主断面为直墙半圆拱形,净宽6.30m,净高7.85m。因火工品无法供应,主排水泵房施工工期受到影响。若暂停主排水泵房施工,井下永久排水系统不能及时形成,存在严重安全隐患。为此,采用高效静力破碎剂,对主排水泵房进行全断面掘进施工;在保证安全、质量的前提下,顺利完成了施工任务。The main water drainage pumping chamber in Menkeqing Mine had a designed length of 69.868 m,its main cross section was a semi arch vertical wall,the net width was 6.30 m and the net height was 7.85 m.Due to no supply of the blasting material,the construction period of the main water drainage pumping chamber was affected.If the construction of the water pumping chamber was paused,thus the permanent water drainage system could not be timely established and there was serious danger existed.Therefore,a high efficient static cracking agent was applied to the full section excavation construction of the main water pumping chamber.Under the premise of ensuring the safety and quality,the construction of the water drainage pump was successfully completed.
