我国金属矿山防治水技术的现在与未来

我国大量的有色金属资源赋存于广泛分布的石灰岩溶地区,这些地区的岩溶水对矿山生产与安全带来严重的威胁。因此,矿山防治水工作显得格外突出和重要。多年来,业已采用的防治水技术有矿床疏干技术和帷幕注浆技术。单一的疏于技术已被我国金属矿山广泛应用;而采用疏、堵结合的大规模综合治理方案,在岩溶地区的一些大水矿山也逐渐推广应用。实践证明,帷幕注浆技术的实施既可减少矿井的涌水量,又可有效地保护环境,因而是一种具有良好发展前景的治水方案。

THE PRESENT SITUATION AND FUTURE DEVELOPMENT OF WATER PREVENTION AND CONTROL TECHNIQUE IN CHINA'S MINES

A huge amount of non-ferrous metal resources are distributed widely in limestone cavern areas in China, and cavern water causes serious threat to the mine production and safety. Therefore,water prevention and control in many mines are of paramount important Water prevention and control techniques which have been used for many years include deposit dewate ring and curtain grout. Widespread application of the dewatering system as single method was practised in metalliferous mines in China. A large scale comprehensive control scheme consisting of dewatering in combination with sealing, has been gradually adopted in some mines where inflow of water is large in the limestone cavern areas. It is shown that the application of curta grout technique could reduce inflow of water in mine as well as protect environment effectively, and proves to be a water control scheme with good development prospect.
