  1. Abstract : incompatible element nh11 and hybrid stress element 18 were employed to analyze rock burst occurring in coal face 9108 of sanhejian coal mine. compared with the results from ansys, the two optimized fems can execute more accurate numerical simulation in the research of rock burst as well as other rock problems and lessen the errors from inaedquately meshing in huge calculations due to the limitation of labor and computer time. in addition, the criterion of averaged generalized stress rate was proposed and used to determine the site and moment of rock burst. the given conclusion is in accordance with the face of coal face 9108 very well

    文摘:利用優化非協調元和雜交元分析了三河尖礦沖擊礦壓，並與ansys程序的計算結果進行了比較.認為優化有限元在沖擊礦壓乃至巖石材料的數值模擬中能給出更為精確的結果，也可減小大型計算中由於人力、機時所限粗分網格產生的誤差.分析中，採用了廣義平均應力率準則來判斷沖擊點位置和沖擊時刻，所得結論與實際情況吻合
  2. Abstract : the stimulation treatment of & quot; loosening rock by the dilatancy of explosive waves & quot; is tested in the casing well 4242 for studying its result and its influence on casing. the result of the field test shows that this test is successful in technology, the oil production of the well is 4 times as much as that of it before the test ; the deformation of casing is local, and the result of the strength calculation shows that the deformation will not destroy casing

    文摘:為了研究「壓脹松動」增產技術的增產效果和對套管的影響，在延長石油管理局子長油礦對4242井進行了現場實驗.該技術採用強動載波在地層深處疊加的方法，造成壓脹條件，松動巖石，增大近井帶滲透率，提高油井產量.施工后，該井產量增加為原來的4倍多.本次實驗工藝上是成功的，首先是按設計要求引爆了炸藥，其二是由於採取了保護措施，使套管變形局限在施工段處，不影響下泵，不影響油井生產;套管強度校核分析也證明了套管不會破壞.施工后地質效果明顯
