    • A method for remotely monitoring conditions such as carbon monoxide or methane gas concentration, longwall roof support pressure, machine parameters or uncut coal, trona or potash layer thickness in a natural resource mining system such as a longwall or continuous mine system. The method utilizes a plurality of sensors connected to low magnetic moment transmitters, e.g. 0.1 ATM.sup.2, or high magnetic moment transmitters, e.g. 2.5 ATM.sup.2, that transmit collected data during multiple short burst transmission periods. Prior to transmission, the data is converted to a digital word format. An algorithm in the transmitter microcomputer ensures that random time intervals exist between data transmission bursts thus preventing a data transmission clash at the central receiver. A microcomputer algorithm in the central receiver protects against data contention caused by simultaneous transmission from several sensors. The data is transmitted to the central receiver either through a natural waveguide pathway or through a utility conductor that is magnetically coupled to the transmitter and central receiver by properly oriented electrically short magnetic dipole antennas. The method can be used, for example, to automatically control the positioning of a plurality of longwall roof supports or to transmit data from a longwall drillhead, along the drill rod, to the central receiver. Data can be communicated between a remote location and a surface area by utilizing a system of repeaters inductively coupled to a utility conductor. Use of the repeater system permits operation of mining machines from a surface computer.
    • 一种远距离监测天然资源开采系统如长壁或连续矿井系统中一氧化碳或甲烷气体浓度,长壁屋顶支撑压力,机器参数或未切割煤,天然碱或钾盐层厚度等条件的方法。 该方法利用连接到低磁矩发射机的多个传感器,例如, 0.1 ATM2或高磁矩发射机,例如。 2.5 ATM2,在多个短突发传输期间发送收集的数据。 在传输之前,数据被转换成数字字格式。 发射机微计算机中的一种算法确保数据传输突发之间存在随机时间间隔,从而防止中央接收机的数据传输冲突。 中央接收机中的微计算机算法可以防止由多个传感器同时传输引起的数据争用。 数据通过自然波导路径或通过适当定向的电短磁偶极子天线磁耦合到发射机和中央接收机的公用设施导体传输到中央接收机。 该方法可以用于例如自动控制多个长壁屋顶支撑件的定位或者将数据从长壁钻头沿钻杆传送到中央接收器。 可以通过利用电感耦合到公用设施导体的中继器系统在远程位置和表面区域之间传送数据。 使用中继器系统允许从平面计算机操作采矿机。
