    • The apparatus uses electric power lines (100) to send and receive command, control, and data signal structures. Message signals are superimposed upon the AC power signals present on existing power lines (100). Transmit and receive sets (10 and 20) are equipped with a unique individual coding to complete the communication links. When a message signal is sent onto the line (100) the unique code of the sending unit (10) is placed at a predetermined position in the transmitted signal. Also the intended receiving unit code is placed in the message signal. An individual receiving network at a given location will be activated only when its unique code has been placed into a message on the line (100) sent by another unit. This coding ensures that only the intended location receiver will be able to trap the signal. The signals will be mid to high frequency and will be composed of low level logic/digital bits.

    • The apparatus uses electric power lines to send and receive command, control, and data signal structures. Message signals are superimposed upon the AC power signals present on existing power lines. Transmit and receive sets are equipped with a unique individual coding (for identification and security) to complete the communication links. When a message signal is sent onto the line the unique code of the sending unit is placed at a predetermined position in the transmitted signal, such as in the header. Also the intended receiving unit code is placed in the message signal. In this manner, an individual receiving network at a given location will be activated only when its unique code has been placed into a message on the line sent by another unit. This coding ensures that only the intended location receiver will be able to "trap" the signal. The signals sent will be mid to high frequency and will be composed of low level logic/digital bits.
    • 该装置使用电力线发送和接收命令,控制和数据信号结构。 消息信号叠加在现有电力线上存在的交流电力信号上。 发送和接收设备配备了独特的个人编码(用于识别和安全)来完成通信链路。 当消息信号发送到线路上时,发送单元的唯一代码被放置在发送信号中的预定位置,例如标题中。 此外,预期的接收单元代码被放置在消息信号中。 以这种方式,只有当其唯一代码被放置在由另一单元发送的行上的消息中时,才能激活给定位置处的单个接收网络。 该编码确保只有预期的位置接收器将能够“陷阱”信号。 发送的信号将是中高频,并由低电平逻辑/数字位组成。

    • Ore may be mined from an irregular ore body using a mining structure which conforms to the shape of the ore body, and which relieves stress that might otherwise hinder caving through bridging and compacting. The conic mass caving structure comprises a series of ore passes, extending from an upper position to a lower position in a tapered fashion. The ore passes intersect each of a series of hyperbolic drifts, which are shaped to surround the portion of the ore body to be mined. The hyperbolic drifts are parallel, and each hyperbolic drift surrounds a smaller area then the hyperbolic drift directly above it, to form an essentially conic shape. Secondary drawpoints are located at the intersection of each ore pass and each hyperbolic drift, while the primary drawpoints are located in a apex surrounded by the lowermost hyperbolic drift. Ore may be drawn from the secondary drawpoints, and either conveyed to the apex through chutes in the ore passes, or transported through crosscuts to a haulage mechanism in a shaft rising to the surface of the ground. The primary haulage mechanism to be utilized will consist of a conveying mechanism running through the haulage drift extending from the apex to a shaft, through which ore is removed vertically to the surface.
    • 矿石可以使用符合矿体形状的采矿结构从不规则的矿体中开采,并且通过桥接和压实可以减轻可能阻碍塌陷的应力。 锥形质量凹陷结构包括一系列矿石通道,其以锥形方式从上部位置延伸到下部位置。 矿石通过一系列双曲线漂移中的每一个,其被成形为围绕要开采的矿体的部分。 双曲线漂移是平行的,并且每个双曲线漂移围绕更小的面积,然后双曲线漂移直接在其上方,以形成基本上圆锥形的形状。 二次点位于每个通过点和每个双曲线漂移的交点处,而主要点位于由最低双曲线漂移包围的顶点中。 矿石可以从次要边界抽出,并且通过矿石通道中的滑槽传送到顶点,或者通过横切传送到在上升到地面的轴中的牵引机构。 要使用的主要运输机构将包括一个输送机构,其运行通过从顶点延伸到轴的运输漂移物,矿石通过该运输机构垂直地移动到该表面。
