Thesis (M.Sc.)--Chulalongkorn University, 2004

One of the important environmental impacts in a coal mining area is acid mine drainage (AMD). AMD causes the contamination of heavy metals in surface water, ground water, and soil. This thesis investigates the effectiveness of using municipal solid waste (MSWFA) and cement kiln dust (CKD) by to improve the engineering properties of soil and to test leaching experiment. The engineering properties consist of a compaction test for finding the appropriate amount of water for preparing the sample. The leaching tests compose of two experiments that are leaching test and column test. Leaching test based on the 6th Notification of the Ministry of Industry, B.E. 2540 (1997), and column leaching test stimulate extraction solution like acid rain scenario. The results of compaction tests revealed that increasing the CKD increased the optimum moisture content and maximum dry density but increasing the MSWFA caused the optimum moisture content to increase but reduced the maximum moisture content. From the Atterberg limits, it was found that the amount of CKD and MSWFA cause decreases in the plastic indexes due to increases in the plastic limits. Increasing the amount of CKD can increase unconfined compressive strength but increasing the amount of MSWFA caused a decline in unconfined compressive strength. According to leaching tests and column leaching tests, the concentration of Fe and Mn were reduced when increasing the amounts of CKD and MSWFA. The reducing of concentration of Fe and Mn depended on increasing of pH and curing time. The column leaching test confirms the results of leaching tests
