DGC Desorbable Gas Content Determination Apparatus Compliance Standard: GB/T23250-2009 "Direct Method for Determining Coal Seam Gas Content Underground" The DGC desorbable gas content determination apparatus collects coal cores from deep underground through direct drilling, measures the gas desorption rate and desorption volume of the coal cores, and uses a specific mathematical model to calculate the gas loss before the coal sample is sealed in the sample canister. Main technical indicators: Determination time: <8h
Basic parameters of the DGC desorbable gas content determination apparatus:
(1) Underground desorption system
(2) Surface gas desorption system
(3) Weighing system
(4) Coal sample crushing system
(5) Moisture determination system
Technical requirements for the DGC desorbable gas content determination apparatus:
1. The coal sample canister must maintain airtightness under 1.5 MPa air pressure.
2. Coal sample crushing should achieve 95% of the sample passing through a 60-mesh (0.25mm) sieve. Two backup crushing systems are required.
3. Test data must be reliable and accurate, meeting standard requirements.
