The Taigemiao Mining Area of Xinjie is difficult to develop safely and efficiently because of overlapping coal and natural gas mining rights. Aiming at the problem that coal-gas overlap is difficult to develop two kinds of resources safely and efficiently, a systematic study is carried out by means of investigation, statistical induction and theoretical analysis. We study the disaster factors, disaster processes and potential risk types of natural gas Wells during coal and natural gas cross-exploitation in overlapping areas. Based on the constraint conditions of natural gas production layer, overburden aquifer, coal seam disclosure, exploitation disturbance and plugging standard, we put forward the three-dimensional whole-well optimization plugging technology. Then, we conducted field tests on abandoned natural gas Wells, and the main parameters met the requirements. Finally, we further put forward the technical system of over abandoned well and disaster prevention in the mining face. This paper has a certain practical reference significance for the safe development of coal and natural gas in the overlapping area of mineral rights in this region.
