矿井井筒涌水量预测方法的研究,是一个带普遍性的十分重要的课题,对于加快矿井井筒建设速度具有重大的经济意义和现实意义。“七、五”期间,我国煤炭系统有能力达一亿多吨的45个立井井筒需要建设。而在目前的井筒涌水量预测工作中,存在着许多问题,预测质量低劣,难于制定出合理的井筒施工方案,以致在施工中极大地影响着井筒施工装备潜力的发挥和建设速度的提高,造成工期延长,投资加大,矿井不能按期移交生产。随着井筒施工深度的加大,水对施工的影响问题将更大,水文地质条件也更加复杂。另一方面,我国从解
The research on prediction method of mine shaft water inflow is a very important issue with universality. It is of great economic and practical significance to speed up the construction speed of mine shaft. During the “Seventh and FIVE-Year Plan” period, 45 well shafts in our country’s coal system capable of more than 100 million tons need to be constructed. However, there are many problems in predicting wellbore water inflow at present. The prediction of quality is poor and it is difficult to work out a reasonable wellbore construction scheme, which has greatly affected the potential of wellbore construction equipment and the construction speed in construction, resulting in Duration extended, investment increased, the mine can not be handed over to the production schedule. As the depth of wellbore construction increases, the impact of water on construction will be greater and the hydrogeological conditions will be more complicated. On the other hand, our understanding
