To enhance the productivity and economy of LA production, many extensive studies have investigated the potential of utilizing less costly raw materials, such as starchy, cellulosic materials and molasses.
Among the above-mentioned raw materials, lignocellulosic biomass is an inexpensive and widely available renewable carbon source.
Lignocellulosic biomass is composed of cellulose, hemicellulose, and lignin as the main components and is considered one of the preferred raw materials for producing LA as it contains large amounts of fermentable sugars.

Taking a certain old goaf in ZiBo as an example, the article in detail introduced the process of old goaf management, proposed methods of regulating the quality of filling materials, constructing a new downhole water filter wall and controlling concentration of solution value in 53% to 55%, to strengthen the quality of concentration of solution.
The glue powder is provided by ZiBo Haizhou cementing material corporation.
In order to ensure the quality of cement-sand ratio and slurry concentration, the construction workers take same type of vertical chain mixed machine and vertical two-way mixed machine’s filling ability into consideration to calculate the demand of backfilling, glue materials per hour.
