为及时、准确地提供煤厚变化数据,分析其变化规律,煤炭部渭南煤矿专用设备厂成功地研制出一台“单道数字式煤厚探测仪”。该仪器具有体积小,重量轻,携带方便,操作简单等优点。一年来,我们在焦作冯营、马村、王封、焦东等矿作了14条剖面,300多个观测点的试验证明,应用效果良好。与矿井钻探相比,不仅提高了探测煤 In order to provide timely and accurate data on coal thickness variation and analyze its variation, the Weinan Coal Mine Special Purpose Equipment Plant of the Ministry of Coal Mining has successfully developed a “single-channel digital coal thickness detector.” The instrument has a small size, light weight, easy to carry, easy to operate and so on. In the past year, we conducted 14 sections in the camps of Fengying, Macun, Wangfeng and Jiao Dong in Jiaozuo. Experiments of more than 300 observation points have proved that the application effect is good. Compared with mine drilling, not only improve the detection of coal
