二号盲井位于松树脚矿1—4矿体北部,其南侧留有保安矿柱,井筒及附属巷道设置于设计开采影响范围之外,矿体开采后该井附近地区出现了明显的地压活动,岩移超出预想边界。为保证井巷安全曾上报了处理方案。通过调查研究预计了岩移发展趋势,于1980年9月后陆续提出了修改方案。这些方案正在付诸实施,预计的岩移发展趋势也已初步得到验证。
The No. 2 blind well is located in the north of No.1-4 ore body of Songchu Feimou and has the security pillar on the south side. The wellbore and the auxiliary roadway are set outside the influence area of design and mining. After the orebody mining, obvious land Pressure activities, rock moved beyond the expected boundary. In order to ensure the safety of the shaft has been reported to deal with the program. Through the investigation and study, the development trend of rock migration is predicted. After September, 1980, the revision plan has been put forward one after another. These programs are being implemented, and the expected rock drift development trend has also been tentatively verified.
