井下煤仓堵塞是煤矿安全生产中长期未得到解决的难题。 1986年,邢台矿务局在郑州市荥阳空气炮厂的协助下,在显德汪煤矿井下经常堵塞的一号煤仓安装了两台ZJ-019系列的Ⅱ型防爆空气炮,两年多来的使用证明:用空气炮疏通煤仓堵塞具有安全、可靠、迅速、高效的优点,对煤矿生产具有显著的经济效益。为了总结使用经验,河北省煤炭工业厅于1988年12月9日在邢台矿务局显德汪煤矿召开了《空气炮在井下煤仓应用推广评议会》。评议会由科技处处长、教授级高级工程师施能为同志主持。参加会议的单位有峰峰、邯郸、井陉、兴隆、邢台、下花园、八宝山等局(矿)和厂家代表,共28人。
Blockage of underground coal bunker is a long-term unresolved problem in coal mine safety production. In 1986, Xingtai Mining Bureau installed two ZJ-019 series Ⅱ explosion-proof air guns with the help of the Shenyang Gun Air Cannon Factory in Zhengzhou City, at the No. 1 bunker, which is often blocked in the Xiandewang coal mine. For more than two years The use of proof: the use of air gun to clear the coal blockage has the advantages of safe, reliable, rapid and efficient, and has significant economic benefits for the production of coal mines. In order to summarize the use of experience, coal industry in Hebei Province on December 9, 1988 Xingtai Mining Bureau Xingde Wang mine held “application of air gun in the underground coal appraisal Council.” The council is chaired by the Director of Science and Technology Department and Professor-level Senior Engineer Shi Neng. Participating units are Fengfeng, Handan, Jingxing, Xinglong, Xingtai, under the garden, Babaoshan Bureau (mine) and factory representatives, a total of 28 people.
