Title: 一种微波热风耦合注热的煤体增透方法
Inventor: YING BOQUAN
IPC: E21B43/24
Filed: 2017-06-26
Abstract: 公开了一种微波热风耦合注热的煤体增透方法，首先向煤层（1）施工钻孔（2），在同轴波导（5）前端连接微波天线（4），一起送入钻孔（2）。再依次将波导转换器（7）、矩形波导（8）和微波发生器（9）连接在同轴波导（5）外端。接着将热风管（3）用管道连接，通入钻孔（2）内部。设备安装完毕之后，向钻孔（2）输送高压热风，同时打开微波进行辐射。微波辐射可以有效促进瓦斯解吸，产生的热应力更是能够损伤煤体，产生微裂纹，同时高压热风会沿着煤层裂隙快速流动，吹走裂隙中煤屑，扩大煤层裂隙。将这两者相结合，微波不仅对煤体产生辐射效果，而且起到了进一步加热风流的效果，使得煤体孔隙更易疏通，达到良好的煤体增透、促进瓦斯解析的效果。

Abstract: Provided in the application are a method for sending and receiving a reference signal, a network device, a terminal device and a system. The method, the network device, the terminal device and the system are applicable to SRS resource configuration in NR. The method comprises the steps that: the terminal device sends an SRS according to the position of a starting subcarrier transmitting the sounding reference signal SRS; wherein the position of the starting subcarrier transmitting the SRS is determined by the offset of a sounding region, the offset of the sounding region indicates the amount of resource that the starting subcarrier of the sounding region offsets relative to the starting subcarrier of a bandwidth portion BWP of the terminal device, and the sounding region is a resource for transmitting the SRS.
