| The Shanjiaoahu coal-mine is ageing. Its geological structure is complicated, the coal-seam composed and stored lies unstable state; Total annual production is 800,000t, the annual output of per capital is fewer than 300t,The enterprise has been deficit for along time.It is an effective way for the state-run coal enterprise to change the style of economic increase by building up the mine with high production and efficiency. Also it is the objective requirement which meets economic development of the market, and tackle the international, domestic market competition after the accession to the WTO. If the old mine should extricate itself from predicament, it must take the way with high production and efficiency unswervingly too. This text has analyzed the restricts factor of construction of ShanJiaoShu coal-mine with high production and efficient and reserarched the way and countermeasure which realizing the goal of high production and efficiency And then put forward the solution which make the technological transformation by improving the efficiency of extractive working of the equipment of full mechanized mining working face on the basic of correctly choosing the equipment of full mechanized mining working face. Confirming reasonable the paramenters of full mechanized mining working face and the craft of working.Given play to the ability of the existing equipment to the maximum extent, improve the efficiency of the mine and benefit level. At the same time, discussed and made the scientific scheme, organized implementation in scene production. Through prediction and analyses, it is proved that way and measure of high production and efficiency is reasonable and feasible under the complicated terms, The mine of Shanjiaoshu to put forward to in technical and economic index, we can make the good economic benefits. So, the research of this subject, have very important realistic meanings in revitalizing the panjing, revitalizing the coal industry of GuiZhou.
