Recently, the “Intelligent Explosive Device†designed and invented by He Yiqing, a young worker of the Tianchen Coal Mine of the Zao Mine Group, obtained the national patent.
He Yiqing, 36, is an ordinary worker in the Department of Prevention and Control of Tianchen Coal Mine. In addition to his work, he gave full play to his expertise in weak current and mechanical maintenance, and devoted himself to technological innovation and technological improvement. He successfully docked the gun and the portable instrument and developed a smart detonator. This device integrates gas detection and detonator explosion function. Once the gas in the field exceeds the limit, the detonator will automatically alarm and stop immediately, safe and reliable. After the project has been promoted, it can ensure the safety of shooting on the mining face and avoid major accidents.
