摘要
为了保证二采区1202运巷掘进安全,防止巷道掘进期间水害事故发生,潞安集团司马煤业公司地测科决定对1202掘进工作面布置扇形探水钻孔,对其顶板及周围积水进行探放,并在探水施工期间采取了合理有效的安全措施。通过探放水施工后消除了巷道顶板及周边水患影响,有效提高了巷道掘进效率,避免了巷道透水事故发生,取得了显著效果。
In order to ensure the safety of 1202 roadway driving in the second mining area and prevent water damage accidents during roadway driving, the geological survey department of Lu'an Group Sima Coal Industry Company decided to arrange fan-shaped water exploration boreholes on the 1202 roadway driving face, to explore and discharge the roof and surrounding water, and took reasonable and effective safety measures during the water exploration construction. After water exploration and drainage construction, the influence of roof and surrounding water disasters was eliminated, the tunneling efficiency was effectively improved, and the occurrence of water permeation accident was avoided, and significant results were obtained.
