涞源石棉矿是解放后,由资本家手中接收过来的小矿,摊子破乱,没有厂房,没有设备.矿山采的很乱,没有任何资料可查.尤其是该矿地质构造复杂,大小断层纵横交错,折曲形式不同,倾斜变化大,最大倾斜70-80°,最小10-15°,生成不同形式的矿脉,如复边式单边式,细脉和环状脉等.矿脉层厚度不均,从0.5-3.7公尺,而且断续不连贯,时富时贫,加之棉绒特点细而滑,钻探取不出样品.在这样的矿床上进行勘探工程,工作量是相当大的.且一时也不容易探清.没有清楚地质资料,就不能投资建设井巷.在这种情况下,我们采用了开小矿的形式,边采边探,积累地质资料,从中摸索了如下几点经验:
Asbestos source Asbestos mine is liberated, by the hands of the capitalists received over the hands of small mines, mess, there is no plant, no equipment mining mining chaos, there is no information to be found, especially the mine complex geological structure, the size of the fault aspect Staggering, different bending forms, large inclination changes, the maximum inclination of 70-80 °, the minimum 10-15 °, to generate different forms of ore veins, such as the complex edge type unilateral, veins and ring vein, etc. The thickness of the veins All from 0.5-3.7 meters, and intermittent incoherent, when rich and poor, combined with the characteristics of fine and smooth cotton lint, drilling can not take the sample in such deposits on the exploration project, the workload is considerable. And not easy to find out a moment.Without the clear geological information, we can not invest in the construction of roadway.In this case, we used to open a small form of mining, mining and exploration side, accumulation of geological data, from the groping of the following points experience:
