本刊曾在今年第三期上发表了昆明工学院周君才同志所写出的一篇富有创造性的文章:“急倾斜薄矿脈开采中深孔应用问题”。某矿的矿床是属于急倾斜薄矿脈的,他们以前都用浅孔留矿法或混采充填法回采。该矿后来根据周同志的建议进行了尝试性的试验,试验结果初步证实了这一方法在安全、经济、生产率等方面的理论上的论证。该矿这种理论与实践相结合的作法是很好的。虽然该矿目前尚存在一些问题,但如果能大力钻研,早日解决这些问题,对发展和推广深孔采矿使用的范围,将有重大的意义。为此,我们将某矿的试验经过及存在的问题发表于后,希望该矿及其他有关矿山,根据自己的条件,继续进行研究,俾便这一方法的理论和实践都能得到进一步的完备和充实。
In the third issue of this year, the magazine published a creative article by Comrade Zhou Juncai from Kunming Institute of Technology: “Application of Deep-hole in Deeply-Lean Thin Vein Mining.” The deposits of a mine belong to the steeply dipping thin veins, and they have been recovered by shallow-hole retention or mixed mining before. The mine later conducted a tentative experiment based on the suggestion of Comrade Zhou, and the preliminary results of the experiment proves the theoretical proof of this method in terms of safety, economy and productivity. The combination of this theory and practice of the mine is good. Although there are still some problems in the mine, it will be of great significance to study and solve these problems as soon as possible, which will have great significance for the development and promotion of the scope of deep-hole mining. For this reason, after we published the experimental and existing problems of a mine, we hope that the mine and other relevant mines will continue to conduct research according to their own conditions so that the theory and practice of this method can be further improved And substantial.
