Study and application of a new type of foamed concrete wall in coal mines

Journal of Coal Science & Engineering(China) 2013年第3期19卷 345-352页

作者： Zi-Bo TANG Yong-Liang ZHAO de-shun kong Dan KAN Baodian Coal Mine Yanzhou Coal Mining Company Limited Jining 273513 China

A new type of airtight wall with the combination of foamed concrete and pier support was designed in this study. Based on the theories and models related to the foamed concrete and blasting shock load, using the numerical analysis method, this study obtains the new material＇s mechanical and destruction laws through analyzing its reaction to different conditions of load （mining and shock waves）, airtight wall thickness （1.2, 1.5, 1.8, 2.1 m） and steel pipe diameters （400, 450, 500 and 600 mm）. The results show that： ①foamed concrete can have very good suspension, and the pier column support is the main carrier of roof pressure; ② the damaged area of foamed concrete decreases as the foamed concrete thickness increases. Under impact loading, the thickness of the foamed concrete wall plays a more obvious role in retaining its integrity; ③under the same mining pressure, the damage area increases as the steel pipe diameter increases; ④ with additional mining stress increase, under whether static load or impact load, the stress on the foamed concrete and steel pipe will also increase gradually, therefore the actual airtight wall design will need to be based on specific circumstances in steel stress.
