The invention discloses a coal seam heating and pulverized coal removing method. The method comprises the following steps that firstly, the length of a coal seam to be subjected to thermal recovery isL, a ground control center, a generator and a ground wire winding vehicle are arranged on the ground above the coal seam, an intelligent cable winch is arranged on the ground wire winding vehicle, ahigh-temperature-resistant tensile cable is wound around the intelligent cable winch, and a first tension sensor is arranged at the wire outlet end of the intelligent cable winch; and n hollow pipeline robot groups are assembled, one end of the high-temperature-resistant tensile cable is connected with the generator, and the other end of the high-temperature-resistant tensile cable is connected with the rearmost hollow pipeline robot group. In conclusion, the method is high in automation degree, convenient to operate and good in pulverized coal removing effect, and the coalbed methane mining efficiency is improved.

    煤层加热及煤粉清除方法,包括以下步骤:步骤一、待热采的煤层长度为L,将地面控制中心、发电机以及地面卷线车置于煤层上方的地面上,其中地面卷线车上设置有智能电缆绞盘,智能电缆绞盘上缠绕有耐高温抗拉电缆,智能电缆绞盘的出线端设置有第一拉力传感器;装配好n组中空式管道机器人组,耐高温抗拉电缆的一端与发电机相连接,耐高温抗拉电缆的另一端与最后方的中空式管道机器人组相连接;综上所述,本发明自动化程度高、便于操作、煤粉清除效果好、提高了煤层气开采效率。
