In order to reveal the law of coal accumulation in the Jurassic coal seam of the new coal mine of Hegang coal field, the coal seam in the coal mine of the new coal mine is much more difficult. Using the theory and method of sedimentary stratigraphy, coal geology, according to the disclosed Yixin coal mine exploration data, mine production of geological data, analyzes the Jurassic Shitouhezi Formation coal measures strata petrological characteristics and sedimentary environment and poly rules of coal. The results show that the structure of the coal bearing section and the upper coal bearing section is strong and frequent, and the coal forming condition is poor, while the middle coal bearing section is easy to form thick coal seam in the Binhu Delta. Most of the coal seam formed in lake delta topset, extra thick coal seam formation and a large area of wetlands of delta plain.
