预防瓦斯事故的措施德国煤矿预防瓦斯事故的措施有比较先进的技术,也有比较常见的措施。如德国萨尔煤炭公司采用装有光感应装置的掘进机,这种装置灵敏度比较高,能及时预测预报瓦斯浓度;鲁尔公司在井下装设防止瓦斯煤尘爆炸的隔爆水棚(与我国使用的隔爆水棚相似),每个矿要安装2万多个,每个水棚装水80升。安装数量、位置有严格的规定,平时有专人管理。井下使用的设备、仪器、材料都必须是经国家矿用设备材料检验局检验许可
Measures to prevent gas accidents German coal mine measures to prevent gas accidents have more advanced technology, there are more common measures. Such as the German Saar Coal Company incorporates a light-sensing device boring machine, this device is relatively high sensitivity, timely prediction of gas concentration forecast; Ruhr installed underground gas explosion in the explosion-proof proof shed (with China The use of explosion-proof water shed similar), each mine to install more than 20,000, each water shed 80 liters of water. Installation of the number of locations have strict rules, usually someone management. Downhole equipment, instruments, materials must be approved by the National Mining Equipment Materials Inspection Bureau
