使用现有技术对厚、急倾斜煤层进行开采时,容易造成顶板事故。对采空区使用随采随填的处理方法,用传感器控制填充材料的及时填充,可以有效控制顶板事故的发生。在厚煤层中,红外传感器追踪煤炭的位置,带动挡板自动前进,挡板把回风平巷分为前后两段,后段在挡板处自动断裂,填充物随之下落填充。在急倾斜煤层中,金属网隔层随填充物下落,起到隔离填充物和煤炭、控制填充过程结束的作用。 When using the existing technology to mine thick and steep coal seams, it is easy to cause roof accident. The use of goafs with the mining with the filling approach, using sensors to control the timely filling of filler material, you can effectively control the roof accident. In the thick seam, the infrared sensor tracks the position of the coal and drives the baffle to move forward automatically. The baffle divides the breeze return lane into two sections before and after. The rear section automatically breaks at the baffle and the filling falls and fills. In steep coal seams, the metal mesh barrier falls with the filler, isolating the filler and coal, controlling the end of the filling process.
