Dr.ll machines used in sur.ace mines, par.icular.y in coal, is char.cter.zed by a ver. poor.utilization （ar.und 40%） and low availability （ar.und 60%）. The main pur.ose of this study is to develop a dr.ll selec- tion methodology and simultaneously a per.or.ance evaluation technique based on dr.ll cuttings pr.duced and dr.lling r.te achieved. In all 28 blast dr.lled thr.ugh wer. investigated. The dr.lling was accomplished by 5 differ.nt dr.ll machines of Inger.oll-r.nd and r.vathi wor.ing in coal mines of Sonepur.Bazar. （SECL） and Block-II （BCCL）. The dr.lls ar. r.tar. and r.tar. Per.ussive type using tr.- cone r.ck r.ller.bits. Dr.ll cuttings wer. collected and sieve analysis was done in the labor.tor.. Using r.sin r.mler.Diagr.m, coar.eness index （CI）, mean chip size （d）, specific-st tr.ce ar.a （SSA） and char.c- ter.stic par.icle size distr.bution cur.es for.all the holes dr.lled wer. plotted. The pr.dictor.equation for.dr.ll penetr.tion r.te established thr.ugh multiple r.gr.ssions was found to have a ver. good cor.elation with an index of deter.ination of 0.85. A compar.tive analysis of par.icle size distr.bution cur.es was used to evaluate the dr.ll efficiency. The suggested appr.ach utilises the ar.a under.the cur.e, after.the point of tr.nd r.ver.al and br.ttleness r.tio of the r.spective bench to ar.ive at dr.ll ener.y utilization index （DEUI）, for.mapping of dr.ll machine to bench, The developed DEU1 can aid in selecting or.mapping a r.ght machine to r.ght bench for.achieving higher.penetr.tion r.te and utilizations.

The tetr.hydr.quinoline moiety is a str.ctur.l featur. of many natur.l pr.ducts. By using a domino r.action of ar.matic amines and cyclic enol ether. catalyzed by zir.onyl chlor.de in water. var.ous tetr.hydr.quinoline der.vatives wer. synthesized efficiently. Most cyclized pr.ducts showed cis selectivity. The cis selectivity was tentatively r.tionalized due to chelation contr.l in water.
