1. Introduction. Coal gangue is the solid waste generated during coal mining. Coal gangue accounts for approximately 10–15% of coal extraction (Zhou et al., 2014).The accumulation of coal gangue waste requires a substantial amount of land and generates coal gangue leachate (CL) (Jones and Cetin, 2017).Acidic CL (Bouzahzah et al., 2015) …

Co-exploitation of coal measure gases (coalbed gas, shale gas, and tight sandstone gas) puts a higher requirement on drilling fluids. Conventional drilling fluids have disadvantages, such as causing problems of borehole collapse, formation damage, and water blockage. This paper proposes a set of high inhibitive and low-damage drilling …

At the slurry plant, cement, or some other setting agent, is added to the bentonite slurry. The viscosity of the mixed slurry is designed to be in the fluid range during the excavation process. The slurry is then pumped from the mix plant to the excavation. Once the excavation is to full depth, the bottom is cleaned and the process moves on.
