岩溶发育的矿区,水文地质条件复杂,预计矿井涌水量是件重要的工作,也是搞好矿井防水的必要依据。预计过小,防水设施不足而招致淹井;预计过大,将造成国家资金的浪费。为能做好这项工作,采取积累资料、总结规律、运用选优原理,籍穷举法寻找根指数,通过试验与统计,对照部订质量标准要求,而获取适合各矿井使用的预测涌水量计算公式。生产实践表明:穷举法所得公式能满足设计需要,为矿山的安全开发创造了先决的条件。
Karst development of the mining area, the hydrogeological conditions are complex, is expected to mine the amount of water influx is an important piece of work, but also to improve the necessary basis for mine waterproofing. Expected to be too small, inadequate waterproofing facilities caused by flooding wells; Expected to be too large, will result in a waste of state funds. In order to do a good job of this work, we take the principle of accumulating data, summarizing the law, using the principle of selection and preference, looking for the root index by means of exhaustive enumeration, comparing the quality standards required by the test and statistics, and obtaining the predicted water inflow suitable for each mine Calculation formula. Production practice shows that the formula derived from exhaustive method can meet the design requirements and create the preconditions for mine safety development.
