摘要: One or more techniques and/or systems are disclosed for a bio-derived, environmentally friendly soil conditioner to facilitate the removal of overburden (also known as spoil) in tunneling and mining operations. The bio-derived, biodegradable, and non-toxic formula may be injectable into the soil-cutter interface, and can thicken the tunnel water and disperse the soil to improve the removal of the spoil. The biodegradable soil conditioner may comprise: 1) about 45% to about 75% triglyceride oil by weight; 2) about 20% to about 50% super absorbent polymer by weight; and 3) about 1% to about 4% surfactant by weight. Further, the biodegradable soil conditioner may comprise about 0.1% to about 1.0% viscosity thickening agent.
