摘要： Mining equipment adapted for repeated traversing to and fro adjacent to a conveyor arranged along a longwall face in an underground mine, has a mining machine support structure which bridges the conveyor and which has a curtain for guiding airborne dust arising during cutting of mineral by a rotary cutting head mounted on the machine. The air flow passage defined by the curtain has an air flow inducing means therein, such as a fan or water spray.

摘要： A rotary cutter head for a mining machine is provided with a plurality of cutter tools mounted on an annular end component which defines the end of the cutter head remote from the mining machine. Ventilating means are provided comprising air flow guide passages having air flow inducing spray means, the air flow inlets to the guide passages being in an exposed zone in which the action of cut mineral and/or of the newly exposed working face tends to scour the inlets preventing the build up of damp, fine mineral particles and thereby tending to prevent blockage of the inlets.

摘要： A rotary cutter head for a mining machine comprises a hub assembly drivably mounted on a drive section of the mining machine and a barrel component secured around and co-axial with the hub assembly, the barrel component supporting cutter tool-carrying loading vanes. Ventilation means provided on the cutter head comprise air flow inducing means for inducing air flow along a first path section within the barrel component and in a general direction towards the mining machine side of the cutter head, and along a second path section outside the barrel component and in a general direction away from the mining machine side of the cutter head. Air flow deflector means are provided for urging at least a portion of the induced air flow flowing along the first path section towards the air flow flowing along the second path section.
摘要翻译： 用于采矿机的旋转刀头包括可驱动地安装在采矿机的驱动部分上的轮毂组件和固定在轮毂组件周围并与其同轴的筒部件，所述筒部件支撑刀具承载载荷叶片。 设置在刀头上的通风装置包括气流诱导装置，用于沿着筒部件内的第一路径部分沿着朝向切割头的采矿机侧的大致方向，以及沿着筒部件外部的第二路径部分 并且在远离切割头的采矿机侧的大体方向上。 设置有气流导流装置，用于将沿着第一路径部分流动的感应空气流的至少一部分朝向沿着第二路径部分流动的空气流动。
