Title:
AQUEOUS MEDIUM GUARANTEE SYSTEM FOR COAL FACE
Document Type and Number:
WIPO Patent Application WO/2021/083039
Kind Code:
A1
Abstract:
An aqueous medium guarantee system (200) for a coal face. An aqueous medium is used as a working medium. The system comprises: a working medium use mechanism (209); a working medium storage mechanism (205), the working medium storage mechanism (205) being communicated with the working medium use mechanism (209), so as to supply the working medium to the working medium use mechanism (209); and a first monitoring mechanism (206), the first monitoring mechanism (206) being communicated between the working medium storage mechanism (205) and the working medium use mechanism (209), so as to detect the quality of the working medium flowing from the working medium storage mechanism (205) to the working medium use mechanism (209), and when the first monitoring mechanism (206) detects that the quality of the working medium is substandard, supply of the working medium from the working medium storage mechanism (205) to the working medium use mechanism (209) being stopped. The system facilitates reduction of the maintenance cost in a mining operation process.
