几年来,我们为钻孔堵漏曾试验过好几种方法,例如:浓泥浆、麻刀、马粪、踞末及化学速凝剂等,但效果不太显著。1970年我队514机台采用煤块(也用焦炭)、砂子、粘泥球混合堵漏,取得了一定的效果,除了大溶洞地层和大的过水层外,一般都有效。例如,1970年钻进9号孔,孔深自152.76米以上均漏水,用浓泥浆、粘泥球反复处理均无效;也用了锯末和马粪仍然不能堵住漏。后来,向孔里共计投填了块度为25～90毫米的煤块200公斤左右、填灌了粒度1.0～2.5毫米砂子400公斤左右。在填灌过程中,每投几十斤煤块、灌几十斤砂子,再投泥球。这样层层互填,一直将孔填满,然后用搅好粘度约为22～24 For several years, we have tested several methods for drilling plugging, such as thick mud, knives, horse manure, kurti and chemical quick-setting admixture, but the effect is not significant. In 1970, our team 514 machine used coal block (also used coke), sand, sticky mud ball mixed plugging, and achieved certain results, except for the large cave formations and large aquifers, are generally effective. For example, in 1970 holes drilled No. 9, the hole depth of 152.76 meters above the water leakage, with thick mud, sticky mud ball repeated treatment were ineffective; also used sawdust and horse manure still can not plug the drain. Later, a total of 200 kg of lumps of coal with a mass of 25-90 mm were filled into the hole, and 400 kg of sand with a grain size of 1.0-2.5 mm was filled. In the filling process, each vote a few pounds of coal, irrigation a few pounds of sand, and then cast mud ball. This layer of mutual filling, the hole has been filled, and then stir good viscosity of about 22 to 24
