| 摘 要： | 针对夏桥矿(已报废)各水平涌水量较大,拟建立井下蓄排水系统,并利用峰谷时电价差价对矿井排水时段进行优化,以节约排水费用,提出了井下水闸墙上预留放水管数的计算方法,即:探放水管数计算法和水力学计算法2种方法,并对2种方法进行了比较分析。水力学计算法比较符合放水实际,但没有考虑安全余量;探放水管计算法只是粗略概算,但安全系数比较高。实际应用中,宜采用两种方法互相验证,并考虑经济因素综合选定。

| Abstract: | In Xiaqiao coal mine of Xuzhou Mining Group a large amount of water inflow from each level causes substantive expenses for drainage. Therefore, to save the drainage expenses, an under mine storage-drainage system is proposed to optimize the periods of drainage utilizing the electricity price difference between different periods. The calculation methods for underground pre-treatment including the calculation method for the number of probing and drainage holes and the hydraulics method are put forward based on the simple introduction of the under mine storage-drainage system. After two methods are compared and analyzed, it is found that the hydraulics method is closer to the drainage fact whereas the safe superfluity is not considered, and the calculation method for the number of probing and drainage holes is relative sketchy while the security coefficient is bigger. On application, two methods should be mutually validated and taking safe factors into account to make choice. |
