为了评价井下独头巷道和回采工作面由岩石散发到空气中的热量,必须准确地测定该区域的原岩温度。为此,制造了一种探头。构造与原理该探头由一对装有弹簧的臂构成,在每个臂上装有一个半导体温度计,如图1。温度计安装在弯曲并焊接成近似钻孔直径大小的靴状黄铜管里。通过带有弹簧的臂使温度计紧贴钻孔壁;为使其易于在孔内移动,可 In order to evaluate the underground single tunnel and mining face from the rock to the air in the heat, you must accurately determine the original rock temperature in the region. For this purpose, a probe was made. Construction and Principle The probe consists of a pair of spring-loaded arms, each equipped with a semiconductor thermometer, as shown in Figure 1. The thermometer is mounted in a brass-lined brass tube bent and welded to approximate the diameter of the borehole. The thermometer is attached to the borehole wall by a spring-loaded arm; to make it easy to move within the bore,
