Influence of high-intensity coal mining on burned rock spring

In order to explore the influence of high-intensity coal mining on the burned rock spring, the effective protection of groundwater resources was carried ou t, and the change of burned rock and spring before and after coal mining was analyzed by field investigation. The results showed that there were 405 burned rock sprin gs in Yulin and Shenmu and Fugu area before the coal mining in 1994, the total flow was766. 182 L/s.20 years, such as high-intensity coal mining and other factors, the existing burning rock springs was 62 in 2015, the total flow was 145.176 3 L/s.20 years the number of burned rock spring attenuation of 93.58%, flow attenuation of 81. 06%.Based on the hydrogeological characteristics of fractured aquifers, the mechanism of coal mining on the turbid rock was divided into three types, which were cause d by coal mining around burnt rock, caused by mining under burnt rock and groundwater watershed attack caused by coal mining.
